LOCK DEADBOLT PROTECTOR ABSTRACT OF THE DISCLOSURE Mortise lock has a guardbolt which, when depressed, moves a hooked lever inside the lock housing from a first position in which it blocks operation of the deadbolt operator, to a second position in which it clears the deadbolt operator and permits it to operate. This protects against extension of the deadbolt unless the door is closed.
