Yale Locks BS1 Security Nightlatches 60mm Backset


  • Yale's maximum security BS1 nightlatches are British Standard approved to ensure the highest level of security for timber external doors.
  • They are Kite marked to BS 3621:2007 and are recommended by insurance companies.
  • These security nightlatches have been approved by the Police Secured by Design initiative.
  • The Yale lock is key operated from the outside and both key and lever handle operation from the inside with the internal handle being lockable for increased security.

  • The BS1 nightlatches have a 60mm backset, this is the measurement from the edge of the door to the centre of the keyhole.
  • Locks with a 40mm backset are normally used where there is restricted space, such as on a glass panelled door
