From The Anvil 76mm (3 Inch) Sash Locks

3 Inch Mortice Sash Locks with a 57mm Backset

The From The Anvil 3 inch, or 76mm, sash lock has a backset of about 57mm, measured from the edge of the door to the centre of the keyhole or cylinder. From The Anvil recommends a 3" sash lock with its knob sets, so the knob sits further from the frame.

This size comes as a 5 lever sash lock, keyed alike and heavy duty, or as a Euro profile sash lock for a Euro cylinder. Most are CERTIFIRE approved and fire tested to FD-20/30/60.

76mm (3 Inch) Sash Locks: Questions

Which size sash lock do I need?

If you are replacing a lock, measure the backset (from the door edge to the centre of the keyhole or cylinder) and match it: about 45mm for the 2 1/2" (64mm) sash locks and about 57mm for the 3" (76mm) sash locks. From The Anvil recommends a 3" sash lock with its knob sets.

Euro or 5 lever sash lock?

A 5 lever sash lock is worked by its own key and takes a keyhole escutcheon. A Euro sash lock takes a Euro cylinder or thumbturn cylinder, sold separately, and a Euro escutcheon.
