MORTISE CYLINDER

Designed to be used with mortise locks. The mortise cylinder body is round and threaded, allowing it to be screwed into the mortise lock. It is then secured with a set screw, usually located in the edge of the door, so that the mortise cylinder cannot be removed from the outside. Operating a key in a mortise cylinder moves a cam that is normally attached by screws to the rear of the cylinder.
