Bunker K1 Van Tool Storage Stacker Box Grey – Sold Secure Silver, Stackable, EVA-Lined Drawer, AirTag Compatible

Modular. Secure. Built to grow with your toolkit.

The Bunker K1 Tool Storage Stacker Box in grey is the stackable, drawer-based cornerstone of the BUNKER van security system — a rigid steel storage unit that locks together with other K1 units to build a fully modular, independently certified van storage solution tailored to exactly how you work. Compact enough to fit neatly into a wide range of commercial vehicles, capable enough to handle 300kg per drawer, and secure enough to carry dual independent certification, the K1 Stacker in grey is the organised tradesperson's van storage of choice.

Vertical Space. Fully Utilised.

The K1 Stacker's defining advantage is its ability to stack securely with other K1 units, using the supplied stacking fixings to build upward rather than outward — transforming unused vertical space in your van into a structured, stable tower of organised storage. Each unit locks firmly to the one above and below, and the base unit is bolted permanently to the vehicle floor, creating a single anchored installation that behaves as one unified structure. For tradespeople carrying tools across multiple trades or categories, the stacking system means everything has a dedicated drawer and a defined home — no more rummaging, no more wasted time.

EVA Foam Lining — Your Tools' First Line of Defence

Inside each K1 drawer, thick EVA foam lining provides a protective cushion that absorbs the vibrations and movement of road travel, keeping tools exactly where you placed them rather than sliding and colliding across a bare steel base. For precision instruments, drill bits, saw blades, or any tools that can be damaged by impact or contact with hard surfaces, this lining is a meaningful practical upgrade over unlined van storage. The deep drawer runs on precision ball bearings for smooth, effortless operation at any load level — up to the 300kg maximum capacity — making it as comfortable to use at the end of a long day as it is first thing in the morning.

Independently Certified. Police Approved.

The K1 Stacker carries the same dual certification that defines the entire BUNKER range. Sold Secure Silver — the UK's leading independently administered security standard, awarded only after rigorous physical attack testing — confirms the K1 meets a verified level of resistance to forced entry. Secured by Design, the official police crime prevention initiative, provides further third-party endorsement of the box's security credentials. For tradespeople, employers, and fleet managers who need to demonstrate due diligence in protecting company tools and assets, these certifications provide documented, independently verified evidence of performance.

Locked, Bolted and Tracked

Every K1 unit is fitted with a tough integrated security lock — supplied with two keys — holding the drawer firmly closed against unauthorised access. The base unit of any assembled stack is permanently bolted to the vehicle floor using the supplied fixings, securing the entire structure in place and preventing removal of the stack as a unit. A discreet built-in holder in each unit accommodates an AirTag or any Bluetooth trackable device, providing a covert means of locating the box if it is ever taken from your vehicle — an increasingly important layer of protection as tool theft continues to affect tradespeople across the UK.

AirTag not included.

A Professional Finish for Any Van Interior

The grey colourway gives the K1 Stacker a clean, professional appearance that sits naturally in any van interior and coordinates seamlessly with other grey-finish BUNKER products — the T1 Storage Box and S1 Slider — for a unified, matched fit-out. At 905 x 473 x 312mm per unit and 36kg, each K1 has a compact, well-proportioned footprint that suits Transit-sized and equivalent commercial vehicles without dominating the cargo area.

The Complete BUNKER System

Stack multiple K1 units for a full-height organised drawer system, add a T1 Storage Box for lid-access bulk storage, or combine with an S1 Slider for wide-format access to longer tools — building a comprehensive, customised van security setup across the full BUNKER range. Every product in the range is designed to work together, giving you the freedom to configure your van storage around your trade, your vehicle, and the way you work.
