ABSTRACT:
An L-shaped guard plate for reinforcing a door in the area of the door lock assembly. The L-shape provides a strengthening function without introducing any misalignment in the position of the lock bolt of a door with respect to the strike plate carried in a door frame. The device is thus both effective and easily installed on most doors. The guard plate may include integral tabs which engage slots in the housing of the lock unit. The tabs serve to provide increased resistance to the application of rotational forces to the lock unit.
