Abstract
Abstract A protective door shield and mounting for a lock, particularly a mortise lock or double lock, including a generally U-shaped plate that engages the swingable edge of the door in the region of the lock and a plurality of interchangeable inserts seated in openings provided in opposing side panels of the plate. Apertures in the inserts accommodate door knob shanks, lock cylinders, thumb turns and the like. The shield permits the substitution of a lock having a different arrangement of apertures without replacing the door, while it strengthens the door and provides a convenient push plate. Since the inserts are interchangeable, a standardized shield may be readily adapted for use with a wide variety of locks. The lock face plate is received by a recess in the shield and can be surrounded by a trim plate, if required.
