Abstract:
1. A mechanism to be applied to a door jamb that is opposed by a co-operating door edge to strengthen the door jamb to survive forced entry efforts comprising a first elongated plate sized for mounting on a door jamb surface that is opposed by a co-operating door edge, the first plate having a protruding ramp configured to serve as a strike plate for a latch bolt mounted in a co-operating door and a bolt hole in the first plate proximate the ramp to receive the latch bolt when the co-operating door is closed, a second elongated plate having an inner overlay and an outer flange perpendicular to the inner overlay forming an L-shaped cross-section, a bolt hole in the inner overlay to receive the latch bolt when the co-operating door is closed, a slot in the outer flange proximate the bolt hole in the inner overlay sized to receive and surround the ramp of the first plate when the first plate is nested with the second plate and the bolt hole in the first plate and bolt hole in the inner overlay are aligned, both the first and second plates having holes that are sized to receive screws to hold the plates mounted to the door jamb and that are positioned in the first and second plates to align when the bolt holes in the first and second plates are aligned.
