Lockmaster multipoint door lock case for Active door lock. 1-3/4" Backset. This is the gearbox only. Gearbox has latch and hook.
This Lockmaster replacement gearbox features an 8mm double spindle with 62/92mm centers. Double spindle gearboxes are unsprung and therefore not suitable for use with unsprung handles. Your handle set must have a spring cassette otherwise the handles will droop.
Lock is non-handed and latch can be reversed. To do so, undo the screw in the latch to remove. Reverse, reinsert and replace screw.
