Abstract
A lock includes a face plate into which a lock cylinder is mounted. Extending from the rear side of the face plate is a frame for supporting the back of the lock cylinder. A cover plate covers the front of the lock cylinder and includes one or more arms extending through the face plate to the back thereof, where the arms are secured against the plate. By this arrangement, the cover plate is secured to the back of the face plate, preventing removal of the lock cylinder by prying. The frame secures the lock cylinder to the rear, preventing it from being dislodged by hammer blows. Against all such attacks, the full structural integrity of the face plate serves to keep the lock cylinder in place and the lock secure.
