ABSTRACT:
A door is secured against being kicked in by a doorway construction which comprises a conventional wooden door frame side rail defining a door latch bolt hole in a recessed end portion of one of its major faces and a conventional wall including two-by-four studs adjacent the other major face of the door frame side rail, with the minor faces thereof extending parallel to the wall. The weak point of such a frame is in the region of the hole and this is protected by a reinforcement plate extending over a substantial portion of the wall studs and a substantial portion of the minor face of the door frame side rail overlying the hole. The plate is securely affixed to the wall studs and the door frame side rail and covers this region.
