This is an Architectural Quality Sashlock manufactured here in the UK by Willenhall Locks. The latch is operated by the handle and the lock operated by the key.
The narrow body of the lock at 51mm overall makes it very useful for narrow stile doors, or doors with large glass detailing. The backset measurement from the edge of the door to the centre of the spindle and keyhole is 32mm.
Supplied with matching Strike Plate and 2 Keys.
This 5 Lever Lock provides an added level of security over a 3 lever, however is not the same as a British Standard Lock which we recommend for external doors.
