Often used on restroom doors, a message on the outside of the door changes when the lock is engaged or disengaged. Locks open with a turnpiece inside and an emergency access tool outside.

Select a lock with the correct backset distance (the distance from the door’s edge to the center of the lock's mounting hole) for your door. Latch bolt projection is the length the latch bolt extends from the door's edge.
