How it works

Mortise lock case

Backset Deadbolt Latchbolt Cylinder cam Spindle hub

The sprung latchbolt retracts whenever the handle turns, so the door can be pushed shut and opened from inside. The deadbolt only moves when the cylinder cam drives it — which is why the case is marked cylinder actived.
