ABSTRACT:
A strike plate support used in conjunction with a strike plate and a latch bolt or dead bolt. The strike plate for receiving the latch bolt or deadbolt is fastened to the strike plate support which has a portion that is fastened to the back surface of the door jamb. An improvement in door security strength is realized as the strike plate support will prevent breaking of the door jamb caused by sudden concentrated force exerted to the door by unwanted intruders. Optionally, the strike plate support in addition to being fixed to the door jamb can also be secured to the framing lumber for enhanced strength.
