Abstract
A face plate is disclosed for concealing the exposed edge of a lock mechanism when installed within the lock stile of a door. To accommodate the plunger and deadbolt of the lock mechanism, the face plate comprises a plurality of separation lines defining removable portions or "knockouts" corresponding to various lock configurations. Depending upon the configuration of the lock mechanism being used, a corresponding one or combination of the removable portions can be removed to accommodate the particular lock mechanism. In addition, the face plate comprises tabs at the upper and lower edges which hook beneath the vertical edge wall of the door stile adjacent the upper and lower ends of the opening within which the lock mechanism is installed. The tabs hold the upper and lower edges of the lock plate with the opening and can either reduce the number of screws required to secure the face plate to the door or can eliminate the need for screws altogether.
