Choosing the right size of Rack Armour upright protector is the single most important specification decision in any racking protection project. The Rack Armour range covers four main sizes — Small, Medium, Large and Extra Large — plus the larger XXL variant for the heaviest-duty installations. Each size has been engineered to fit a specific range of upright frame profiles, and selecting the wrong size will compromise both the fit and the protective performance. This comprehensive sizing guide is designed to help you understand the full range, identify the right size for your specific racking, and place your order with confidence. Whether you are protecting a small parts store with a few dozen uprights, or specifying a major rollout across thousands of uprights in a heavy-duty distribution centre, the principles set out here will help you get the specification right first time.
Rack Armour is the original, market-leading polymer upright protector for pallet racking. Its proven performance across thousands of UK and European installations is the result of careful engineering — and that engineering depends on each size of protector being correctly matched to its corresponding upright profile. The Small variant fits narrower uprights typical of light-duty racking; the Medium variant covers the most commonly specified upright profiles in mainstream distribution warehousing; the Large variant handles heavier-duty racking with stiffer upright profiles; the Extra Large variant is for the largest standard pallet racking uprights; and the XXL variant addresses the very heaviest industrial racking. Together, this range covers virtually every pallet racking installation found in UK warehouses, distribution centres, cold stores and production facilities.
Hall-Fast Industrial Supplies stocks the complete Rack Armour range in both colour finishes (high-visibility yellow and standard safety yellow) for fast UK-wide despatch. To browse the range now, visit the Rack Armour brand page at hall-fast.com. Our team is on hand to advise on sizing, specifications, project planning and competitive pricing through our market-leading Price Promise. Hall-Fast has helped hundreds of UK customers specify and roll out Rack Armour across applications ranging from small parts stores to multi-site retail distribution networks, and we bring that practical experience to every conversation we have with new customers.
This guide takes a comprehensive approach. We will walk through each size in detail, with notes on the upright profiles each is designed to fit, the typical applications each is specified for, and the operational benefits each delivers. We will then provide a practical decision-tree approach to help you select the correct size for your specific racking, including how to measure uprights and how to handle mixed-size installations. We will conclude with frequently asked questions, a recap of the full range, and details of how to place your order through Hall-Fast.
Why Correct Sizing Matters
Before we get into the details of each size, it is worth pausing to explain exactly why correct sizing matters. Rack Armour protects pallet racking uprights through a combination of clip-fit engagement around the upright and energy-absorbing flex of the polymer body when the protector is struck by a forklift or pallet. Both of these functions depend on the protector being correctly sized for the upright.
If the protector is too small for the upright, it will not engage cleanly. The clip-fit edges will not seat fully, the protector will not sit flush to the steel, and the protective coverage of the upright will be incomplete. In the worst case, the protector simply will not fit at all — but in many cases it will fit partially, leaving the user with a result that looks acceptable but does not deliver the engineered protective performance. This is the most common failure mode of an incorrectly-sized installation.
If the protector is too large for the upright, it will not grip the steel firmly. The clip-fit edges will engage but with insufficient retention force, allowing the protector to shift, slide downward over time, or be dislodged by even minor contacts. A loosely-fitted protector also does not absorb impacts as effectively as a correctly-fitted one, because some of the impact energy goes into shifting the protector rather than being absorbed by the polymer flex.
Correct sizing is also a question of physical compatibility with the install tool. The Rack Armour install tools are sized to match the protectors they are designed to fit — the small/medium tool for Small and Medium Rack Armour, the large/XL tool for Large, XL and XXL Rack Armour. If you specify a protector size that you cannot install correctly with the available tool, you will struggle to achieve a clean fit and may damage the protector in the process.
For all of these reasons, the few minutes spent at the specification stage to confirm the right size is invaluable. Measure your uprights, check the dimensions against the Rack Armour size chart, and if there is any doubt, send your measurements to our team and we will confirm the right specification before you order. The cost of getting the size wrong on a project of any scale far exceeds the cost of a five-minute phone call to confirm.
Small Rack Armour: For Light-Duty and Narrower Upright Profiles
The Small Rack Armour is the entry point in the Rack Armour range, designed to fit the narrower upright profiles typical of light-duty pallet racking. Upright depths in the range of approximately 60mm to 80mm are typically protected by the Small variant, which corresponds to the European Euro A category and similar light-duty UK racking specifications.
Despite its name, Small Rack Armour delivers the same impact-absorbing technology and protective performance as the larger sizes — it is simply scaled to fit narrower uprights. The polymer composition, the clip-fit engagement geometry, the energy absorption and dispersal characteristics, and the rebound performance are all consistent with the larger sizes. What differs is purely the dimensional envelope: the cavity that engages around the upright is sized for narrower steelwork, and the overall body of the protector is proportioned accordingly.
Typical Applications for Small Rack Armour
Small Rack Armour is widely specified in retail back-of-house storage, parts stores, archive facilities, light manufacturing supply storage, pharmacy stockrooms, workshop tool storage, light industrial environments and any other application using narrower upright profiles. The traffic in these environments is typically dominated by manual pallet trucks, walkie-stackers and smaller electric forklifts rather than heavy ride-on trucks, but the cumulative damage from frequent low-level contacts can still be significant — and Small Rack Armour absorbs these contacts effectively.
To view the Small Rack Armour in high-visibility yellow, visit the Small Rack Armour hi-vis yellow page. The hi-vis variant is preferred where strong visual cueing is desired, particularly in narrow aisles or busy picking environments where forklift operators benefit from clear visual identification of upright positions.
For the standard safety yellow finish, visit the Small Rack Armour safety yellow page. The safety yellow variant is preferred in customer-facing environments such as trade counters or showroom-adjacent storage areas, and in contexts where a more conventional, less visually intrusive appearance is desired. Both finishes deliver identical protective performance.
Install Tool for Small Rack Armour
Small Rack Armour is installed using the small/medium install tool, available at the small/medium install tool page. The tool delivers a 3-4x productivity uplift over manual installation, dramatically reduces installer fatigue, and ensures consistent fit across every protector. For projects of more than a few units, the tool is essentially mandatory.
Medium Rack Armour: The Most Commonly Specified Size
The Medium Rack Armour is the most widely specified size in the entire range. It fits upright profiles in the range of approximately 80mm to 110mm depth, which encompasses the vast majority of mainstream UK pallet racking installations. This corresponds to the European Euro B and Euro C categories, and to the standard UK profiles used in general-purpose distribution warehousing, retail distribution centres, e-commerce fulfilment, third-party logistics, food production and many other sectors.
If you are specifying Rack Armour for a typical UK distribution warehouse and you are not sure which size you need, the Medium variant is statistically the most likely answer. That said, you should always confirm the actual upright depth before ordering — the dimensional envelope for Medium is wide, but it is not infinite, and there are plenty of installations that need either Small (for narrower uprights) or Large (for stiffer profiles) instead.
Typical Applications for Medium Rack Armour
Medium Rack Armour is fitted across a vast range of UK warehousing applications. General distribution centres, regional retail distribution, online fulfilment centres, third-party logistics operations, food production warehouses, online grocery dark stores, automotive parts distribution, builders' merchant central distribution, pharmaceutical wholesale and many other sectors all routinely specify the Medium variant. Its versatility is a major reason it is the most common size.
In cold storage and chilled distribution applications, Medium Rack Armour is particularly common because the racking specifications used in these environments tend to fall in the Medium dimensional range. The Rack Armour polymer formulation retains its impact-absorbing properties across the full cold-store temperature range, making the Medium variant a near-default specification in chilled and frozen warehouse rollouts.
To view the Medium Rack Armour in high-visibility yellow, visit the Medium Rack Armour hi-vis yellow page. This is the most commonly ordered single product in the Rack Armour range, reflecting the dominance of the Medium-fitting upright profile in mainstream UK warehousing.
For the standard safety yellow finish, visit the Medium Rack Armour safety yellow page. As with all Rack Armour variants, both colour finishes offer identical protective performance — the choice is a matter of preference and operational context.
Install Tool for Medium Rack Armour
Like Small, the Medium Rack Armour is installed using the small/medium install tool. View the tool at the small/medium install tool page. On rollouts of any meaningful scale, this tool transforms what would otherwise be a slow, fatiguing manual job into a fast, consistent and ergonomic process.
Large Rack Armour: For Heavier-Duty Racking
The Large Rack Armour is engineered for heavier-duty pallet racking with stiffer, larger upright profiles. Upright depths in the range of approximately 110mm to 125mm are typically protected by the Large variant, which corresponds to the European Euro D category and similar heavier-duty UK racking specifications. Large is the natural choice when racking has been specified to handle heavier palletised loads, taller rack runs, or applications where structural stiffness drives upright sizing.
Large Rack Armour shares the same polymer technology, impact-absorbing performance and clip-fit installation methodology as the Small and Medium variants — but is dimensioned to fit larger uprights. The wider engagement geometry and proportionally larger body of the protector ensure clean engagement and full protective coverage on heavier-duty steel.
Typical Applications for Large Rack Armour
Large Rack Armour is widely specified in heavy-duty distribution warehousing, beverage distribution, building materials warehousing, multi-level mezzanine support racking, high-bay pallet storage, heavy industrial component stores, brewery logistics and similar applications where uprights need to be larger and stiffer than typical mainstream racking. The forklift activity in these environments often involves heavier loads at the impact point, and the impact energies generated when an upright is contacted can be substantial — Large Rack Armour is engineered to absorb these higher energies effectively.
Some warehouses use Large Rack Armour selectively — for example, on the lower bays of high-bay racking where the largest upright cross-sections are typically used, while specifying Medium or Small on lighter-duty racking elsewhere on site. Mixed-size installations are common in real-world warehouses, and Hall-Fast can supply mixed orders covering whatever combination of sizes you need.
To view the Large Rack Armour in high-visibility yellow, visit the Large Rack Armour hi-vis yellow page. The hi-vis finish is particularly common on Large units fitted in busy heavy-duty distribution environments where strong visual cueing helps forklift operators maintain awareness of upright positions during high-tempo operations.
For the standard safety yellow finish, visit the Large Rack Armour safety yellow page. The safety yellow finish is widely specified in heavy industrial applications where a conventional appearance is preferred or where standardisation across an existing fleet of safety yellow equipment is desired.
Install Tool for Large Rack Armour
Large Rack Armour is installed using the large/XL install tool, available at the large/XL install tool page. This is a separate tool from the small/medium variant — the leverage and arm geometry are matched to the larger protector dimensions. If your project includes both Medium and Large units (a common scenario), you will need both tools.
Extra Large (XL) Rack Armour: For the Largest Standard Pallet Racking
Extra Large or XL Rack Armour is sized for the largest standard pallet racking uprights. Upright depths in the range of approximately 125mm to 140mm are typically protected by the XL variant, which corresponds to the European Euro E category and similar very heavy-duty UK racking specifications. XL Rack Armour is specified where the racking has been selected for very heavy loads, very tall installations, demanding industrial applications or any combination of these factors that drives the use of the largest standard upright profiles.
Despite its larger size, XL Rack Armour is mechanically the same as the rest of the range — same polymer, same impact-absorbing performance, same clip-fit engagement principle. The dimensions are simply scaled up to fit the largest standard uprights, and the larger body of the protector also means a slightly larger volume of impact-absorbing polymer, which contributes to its capability against the higher impact energies typical of heavy-duty environments.
Typical Applications for XL Rack Armour
XL Rack Armour is fitted in very heavy-duty industrial warehousing, high-bay pallet storage, heavy beverage distribution, steel stockholding, aerospace component stores, defence supply chains, heavy manufacturing production stores, container yards, plant hire stockyards and similar environments where the largest standard upright profiles are in use. These applications share certain characteristics: high-value or high-density loads, demanding operational tempos, and the need for consistent racking integrity to support both the operational and safety performance of the warehouse.
Outdoor and exposed applications — for example, container yards, builders' merchant outdoor storage, and semi-covered heavy materials operations — frequently specify XL Rack Armour because heavy-duty outdoor racking tends to use the larger profiles. The Rack Armour polymer is UV-resistant and weather-resistant, retaining its mechanical properties across the full range of UK outdoor conditions, so it is well-suited to these applications.
To view the XL Rack Armour in high-visibility yellow, visit the XL Rack Armour hi-vis yellow page. The hi-vis variant is widely fitted in heavy-duty distribution environments where forklift operators benefit from clear visual cueing about upright positions during demanding operational tempos.
For the standard safety yellow finish, visit the XL Rack Armour safety yellow page. XL units are commonly specified in safety yellow for heavy industrial applications where a conventional appearance fits with the surrounding plant and equipment.
Install Tool for XL Rack Armour
XL Rack Armour uses the same large/XL install tool as the Large variant. View the tool at the large/XL install tool page. One tool covers Large, XL and the XXL variant, simplifying the tool inventory for projects that include multiple heavier-duty Rack Armour sizes.
A Note on XXL Rack Armour
Beyond the four main sizes covered above, the Rack Armour range also includes an XXL variant for the very heaviest industrial pallet racking — uprights with depths above 140mm and beyond the standard envelope. XXL is specified for specialist heavy industrial racking, the very largest high-bay installations, and certain steel stockholding and engineering applications where uprights are larger than typical heavy-duty profiles.
To view the XXL Rack Armour in high-visibility yellow, visit the XXL Rack Armour hi-vis yellow page. XXL is the least commonly specified size in the range, simply because the racking it is designed for is itself a specialist application — but for those environments where it is the right size, no other variant will substitute.
How to Choose the Right Size: A Practical Decision Tree
With four main sizes (plus XXL), choosing the right Rack Armour for your application can seem complicated. In practice, the choice is usually straightforward once you have the upright dimensions to hand. Here is a practical decision tree to guide you through the process.
Step 1: Measure the Upright Depth
Take a tape measure or callipers and measure the depth of a representative upright in your facility — that is, the dimension front-to-back of the upright frame profile. Make sure you measure the actual upright steelwork, not any baseplate, foot piece or bolted-on component. Measure to the nearest millimetre and record the figure.
If your warehouse has racking from multiple installation phases or different manufacturers, measure several uprights in different parts of the facility to confirm whether the dimensions are uniform or whether there is variation. Even small variations can push you across a Rack Armour size boundary, so this step is worth doing carefully.
Step 2: Match the Dimension to the Rack Armour Size
Use the typical size envelopes set out below as a first-pass guide:
• Approximately 60mm to 80mm depth: Small Rack Armour
• Approximately 80mm to 110mm depth: Medium Rack Armour
• Approximately 110mm to 125mm depth: Large Rack Armour
• Approximately 125mm to 140mm depth: Extra Large (XL) Rack Armour
• Above 140mm depth: XXL Rack Armour
These ranges are guides rather than rigid cut-offs, because Rack Armour is engineered with some tolerance to fit slightly different upright profiles. If your measurement falls clearly within one of the ranges above, the choice is straightforward. If it falls right at a boundary between two ranges — for example, exactly 80mm or exactly 110mm — confirm with our team before ordering, as we may have specific guidance for your particular upright manufacturer.
Step 3: Confirm with Photographs and Manufacturer Detail (Optional)
For projects of any scale, we strongly recommend confirming the size by sending us photographs of the upright (front view, side view and any detail shots that show the cross-section) along with your measurements. This takes a few minutes and gives you absolute certainty about the right specification. The cost of an incorrect size order on a large project — re-shipping, re-ordering, project delay — far exceeds the cost of the brief specification check.
If you happen to know the racking manufacturer and model, that information also helps us confirm the correct size. We work with most of the major UK and European racking manufacturers and can usually identify the right Rack Armour size from the racking model alone.
Step 4: Account for Mixed Profiles
If your warehouse uses multiple upright profiles — for example, a main racking area on Medium uprights and a heavy-duty zone on Large uprights, or a mezzanine on XL uprights with general racking on Medium below — you will need a corresponding mix of Rack Armour sizes. Count the uprights of each profile separately and order accordingly. Hall-Fast can supply mixed orders covering multiple sizes in a single delivery, simplifying the procurement process for sites with varied racking.

Mixed-Size Installations: A Common Real-World Scenario
It is worth dwelling for a moment on mixed-size installations, because in our experience supplying Rack Armour to UK customers, mixed orders are extremely common — perhaps even more common than single-size orders. Real-world warehouses tend to evolve over time, with different rack runs installed at different points in the operation's history, often by different installers, sometimes from different racking manufacturers. The result is a facility with multiple upright profiles, and a Rack Armour rollout that needs to cover all of them.
The key to handling a mixed-size project well is to map the installation carefully at the survey stage. Walk the site, identify each rack run, measure a representative upright in each run, and record the size required for each. Some warehouses will turn out to be uniform on a single size; others will have two or even three different sizes. Map them on a simple plan and use that plan to drive both the order and the installation.
Mixed-size installations also affect tool selection. If your project includes only Small and Medium units, you need just the small/medium install tool. If it includes only Large, XL or XXL, you need the large/XL tool. If it spans the whole range — Small or Medium on some racking and Large, XL or XXL on others — you will need both tools. The cost of the second tool is modest and the productivity gain across the larger portion of the project pays for it many times over.
Hall-Fast can supply mixed orders combining multiple Rack Armour sizes, both colour finishes and both install tool variants in a single consolidated delivery. This simplifies project administration considerably compared to placing multiple separate orders. Just provide our sales team with the breakdown of sizes and quantities you need, and we will pull the order together for you.
Operational and Project Considerations Across the Range
Beyond the question of which size to choose, there are a number of operational and project considerations that apply across the Rack Armour range and that are worth thinking through at the planning stage of any rollout.
Lead Times and Stock Holdings
Hall-Fast holds stock of all Rack Armour sizes for fast UK-wide despatch. Standard quantities of any size can typically be despatched the same or next working day, with delivery to most UK postcodes on next-day or two-day services. For very large orders — particularly those covering multiple sizes — confirm stock and lead times at the point of enquiry so that we can confirm despatch timing or, if necessary, plan a phased delivery.
Colour Choice and Visual Standards
The choice between high-visibility yellow and standard safety yellow is purely a matter of preference and operational context. Some sites use hi-vis throughout for maximum visual cueing; others use safety yellow throughout for a more conventional appearance; others still use a mix — perhaps hi-vis on main aisles and safety yellow elsewhere. There is no universally right answer, but the most common pattern we see in busy distribution warehouses is hi-vis yellow throughout.
Installation Logistics and Project Phasing
Larger Rack Armour rollouts are often phased, particularly in operational warehouses where bringing every rack run out of service at once would be impossible. Phasing the installation by aisle, by zone or by night-shift slot allows the project to fit within available access windows without disrupting the underlying operation. The install tool is essential to this approach because it enables installers to complete a rack run within the available access window — often less than thirty minutes per typical rack run.
Documentation and Audit Support
For projects with formal procurement, audit or compliance requirements, Hall-Fast can supply manufacturer datasheets, declarations of authentic Rack Armour product, certificates of conformity for the polymer materials, and other supporting documentation. Just specify what you need at the order stage and we will pull together the documentation pack alongside your delivery.
Ongoing Maintenance and Replacement
Rack Armour is designed for many years of service life, but individual units will eventually need replacement after they have absorbed enough strikes. Maintaining a small stock of replacement protectors plus the appropriate install tool on site allows in-house maintenance teams to swap out damaged units quickly as part of routine maintenance. This is a simple, low-cost, low-skill task once the install tool is to hand, and it keeps the protective coverage of the racking estate at a consistently high level.
The Full Rack Armour Range Available from Hall-Fast
Hall-Fast stocks the complete Rack Armour upright protector range, which means you can specify exactly the right size and colour for your installation without compromise. The range covers every common upright frame profile found in UK and European warehouses, and is available in two colour options — high-visibility yellow for maximum impact alerting and standard safety yellow where a more conventional appearance is preferred. Below is a quick reference to the main product pages on our website:
• Rack Armour Small (Hi-Vis Yellow): small upright protectors — for narrower upright profiles, available in high-visibility yellow.
• Rack Armour Small (Safety Yellow): small upright protectors in safety yellow — same protective performance with a standard safety yellow finish.
• Rack Armour Medium (Hi-Vis Yellow): medium upright protectors — the most commonly specified size, suitable for many standard pallet racking systems.
• Rack Armour Medium (Safety Yellow): medium upright protectors in safety yellow — medium size in the conventional safety yellow finish.
• Rack Armour Large (Hi-Vis Yellow): large upright protectors — for heavier-duty racking with larger upright profiles.
• Rack Armour Large (Safety Yellow): large upright protectors in safety yellow — large size in standard safety yellow.
• Rack Armour XL (Hi-Vis Yellow): extra-large upright protectors — for the largest standard pallet racking uprights.
• Rack Armour XL (Safety Yellow): extra-large upright protectors in safety yellow — XL size in standard safety yellow.
• Rack Armour XXL (Hi-Vis Yellow): XXL upright protectors — for the very largest racking systems used in heavy-duty industrial applications.
• Rack Armour Installation Tool (Small to Medium): small/medium installation tool — the official tool that makes fitting Rack Armour Small and Medium quick and effortless.
• Rack Armour Installation Tool (Large to Extra Large): large/XL installation tool — the official tool for fitting the larger Rack Armour sizes.
Every product on these pages is genuine, original Rack Armour — there are many imitation racking protectors on the market, but Hall-Fast supplies only the authentic, tested and proven product backed by the manufacturer's full specification.
Common Real-World Scenarios
Scenario A: Single-Size Distribution Warehouse
A regional distribution centre is built on uniform Medium-fitting uprights throughout. The project needs 350 Rack Armour Medium units in hi-vis yellow plus the small/medium install tool. The order is placed in a single line, despatched within 24 hours and delivered the next working day. Installation is completed in a single day by two contracted fitters working in parallel.
Scenario B: Mixed-Size Logistics Hub
A large logistics hub has 600 uprights split between Medium-fitting in the main warehouse and Large-fitting in a heavy-duty zone serving a customer with denser pallet loads. The order combines 400 Medium hi-vis units, 200 Large hi-vis units, and both install tools. Hall-Fast pulls the order together, palletises by size for clear handling on site, and delivers everything in one consignment. Installation is phased over two consecutive nights.
Scenario C: Multi-Site Retail Distribution Rollout
A retailer is rolling out Rack Armour across twelve regional distribution centres. A pre-rollout survey identifies the upright profiles at each site, which turn out to be a mix of Medium and Large depending on the age and load profile of each warehouse. Hall-Fast supplies twelve consolidated orders, one per site, covering the relevant size mix at each location, plus install tools as required. The roving installation team works through the sites over three months, with consistent results across all twelve.
Scenario D: Phased Cold Store Rollout
A cold storage facility is upgrading its racking protection in phases as parts of the warehouse become accessible during a multi-month operational restructuring. Each phase orders Medium hi-vis units in the relevant quantity, with the install tool already on site from the first phase. The polymer formulation maintains its impact-absorbing performance at minus 22 degrees, and the tool's productivity is essential at low temperatures.
Scenario E: Heavy Industrial Steel Stockholding
A steel stockholder operates very heavy-duty racking carrying dense palletised stock. All uprights are XL-fitting and the order specifies 180 XL hi-vis Rack Armour units plus the large/XL install tool. The XL polymer body is engineered for the higher impact energies typical of heavy industrial environments, and the safety case for the rollout is strong given the consequences of upright damage in a steel stockholding context.
Scenario F: Online Grocery Dark Store
An online grocery operator is opening a new dark store running 24-hour fulfilment operations from a new-build warehouse. The racking is uniform Medium-fitting and the protection rollout specifies 480 Medium hi-vis units plus install tools. The protectors arrive ahead of go-live and are installed by the contracted fit-out team during the final preparation week, ensuring full protection from the moment the operation begins.
Frequently Asked Questions: Sizing and Specification
How do I know which size of Rack Armour fits my racking?
Measure the depth of a representative upright (front to back), match the dimension to the size envelopes set out earlier in this guide, and confirm with our team if you have any doubt. For most installations, the choice is straightforward once you have the dimension in hand. For boundary cases or unusual upright profiles, send us photographs and measurements and we will confirm.
Can I use a smaller size of Rack Armour on a larger upright?
No. The clip-fit engagement geometry will not work — the protector simply will not close around an upright larger than its design envelope. Even if you could force it, the protective performance would be compromised. Always use the correct size.
Can I use a larger size of Rack Armour on a smaller upright?
No. While the protector might appear to fit, the clip-fit retention will be insufficient and the protector will sit loosely on the upright. It will not stay in place reliably and it will not absorb impacts effectively. Use the correct size.
What if my upright dimension is right at a boundary between two sizes?
Contact our team and we will advise based on the specific upright profile and our experience with similar racking. There is some tolerance in the Rack Armour fit, but for boundary cases it is worth a brief specification check before placing the order.
What is the difference between hi-vis yellow and safety yellow?
The two colour finishes provide identical protective performance. The difference is purely visual — hi-vis yellow is more vivid and stands out more strongly against typical warehouse backgrounds, while safety yellow is more conventional. Choose whichever suits your operational context.
Can I mix colours within a single warehouse or even a single rack run?
Yes, absolutely. Some sites use hi-vis on main traffic aisles for stronger visual cueing and safety yellow elsewhere. Others prefer uniformity. There is no protective performance difference, so the choice is yours.
Are the install tools different for each size?
There are two install tools. The small/medium tool fits Small and Medium Rack Armour. The large/XL tool fits Large, XL and XXL Rack Armour. Most projects need only one tool, but mixed-size projects may need both.
How many Rack Armour units will I need for my warehouse?
Count the uprights — each pallet racking bay is supported by two uprights, but adjacent bays share an upright, so a run of n bays needs (n+1) uprights. Add a five to ten percent spare allowance for damages-in-transit and early replacement. Our team can help with quantity estimates if you give us the bay count and rack run layout.
Can Hall-Fast deliver across multiple sites?
Yes. We routinely arrange direct delivery to multiple sites from a single consolidated order, particularly for retail distribution rollouts or 3PL multi-site projects. This avoids the cost and complexity of consolidating at one warehouse and onward shipping.
How quickly can Hall-Fast deliver Rack Armour?
Standard quantities of any size are typically despatched the same or next working day for next-day delivery to most UK postcodes. Larger orders may need a slightly longer lead time, which we will confirm at the point of order. Contact our team for current stock and timings.
What is the warranty on Rack Armour?
Rack Armour is supplied with the manufacturer's full warranty against defects in materials and workmanship. The protector is designed for many years of service life under normal warehouse operating conditions. For specific warranty details applicable to your project, please contact our team.
Is Rack Armour suitable for use in food-grade or hygiene-sensitive environments?
Yes. The Rack Armour polymer is non-porous, easy to clean, and resistant to common food-grade cleaning chemicals. It is widely fitted in food production, food distribution, dairy, beverage and pharmaceutical environments where hygiene standards are critical.
How long does Rack Armour last in service?
Service life is typically driven by impact accumulation rather than material degradation. The polymer is UV-stable, chemical-resistant and dimensionally stable across normal operating temperatures, so the material itself remains in good condition for many years. Individual units are replaced when they have absorbed enough strikes to need refreshing — typically signalled by visible deformation or scuffing of the protective body.
How do I order Rack Armour from Hall-Fast?
Place orders directly through our website at the relevant product page, or contact our sales team for project quotations, larger orders, mixed-size orders or any specification advice you need. We respond promptly to enquiries and we back our pricing with our market-leading Price Promise.

Whether you are ordering a single Rack Armour upright protector for a small workshop or specifying hundreds of units for a major distribution centre rollout, you will benefit from the same guarantee. Our buying power, long-standing relationship with the Rack Armour brand and lean operational structure all mean that we can pass real savings on to you, and the Price Promise is our way of putting that confidence in writing. We have built our reputation over many years by treating customers fairly and consistently, and we recognise that price is one of several factors that influence purchasing decisions — but we never want price to be the reason you choose a less suitable supplier.
To take advantage of our Price Promise, simply contact our sales team with details of the competing price or quotation. We will review the offer, verify that it relates to a like-for-like authentic Rack Armour product, and confirm our matching price quickly so that you can place your order without delay. We can match prices on quotations, online listings and trade prices alike, and we are happy to provide formal written quotations of our own where required for tender or procurement processes. The Hall-Fast team understands that purchasing decisions in busy operational environments often need to happen quickly, and we work hard to make sure our pricing responses are equally swift.
