Abstract

A security striker plate mounted with the rail of a door frame which includes a peripheral door stop and interior framing studs. The striker plate comprises a mount plate inset within the rail against an inner surface and secured thereto by a plurality first wood screws extending into the studs. A right angular apertured strike plate bears against a right angular surface of the rail and is secured thereto by a plurality of spaced second screws which extend into the studs. A right angular door stop lip extends from the strike plate to reinforce the door stop and a right angular anchor plate extends from the lip and bears against outer portions of the rail and is secured thereto by a plurality of tamper proof security screws which extend into the studs. The hook plate is secured to the studs and has apertures therethrough to supportively receive the second and third screws. The striker plate attachment to the framing in the exterior wall adjacent to door jamb deters the rail and the door therein from being kicked in.
