Abstract: A door frame reinforcing plate used for reinforcing a door frame adjacent a lock striker. The reinforcing plate is comprised of a flat plate section adapted to be secured over an interior flat surface of the frame adjacent the lock striker. The flat plate section has a lock bolt opening therein adjacent a first end of the plate section where the plate is bent at right angle to form a flange to overlie an edge surface portion of the door frame. A plurality of holes are provided in the plate above and below the opening for receiving connecting screws which secure the lock striker. A further series of holes is provided in the plate section to receive fasteners which are secured to the frame from an exterior surface of the frame. The reinforcing plate is not visible from outside the door frame, as it is concealed behind the door frame and behind the usual frame moldings.

Abstract: A synthetic wood board comprised of an extrusion of plastics material having opposed elongated top and bottom flat parallel walls spaced apart by transverse walls. A wood grain simulation pattern is formed in at least one of the top or bottom surfaces of the board. Two of the transverse walls are end walls, and each have integrally formed elongated connectors which interconnect with connectors of an adjacent one of the synthetic wood boards. A central fastener receiving channel extends longitudinally in the top and bottom walls and aligned back to back. A transverse wall is provided on each side of the fastener receiving panel. The fastener receiving channel of at least the top wall is provided with a cover strip which is removably connectable across a top opening thereof to conceal fastener heads of fasteners secured therein.
