ABSTRACT:
A lock strike construction is for use with a wall having at least a cripple in the framing thereof and adjacent to a door casing side rail separated from the cripple by an intervening space. A door panel cooperates with the casing and has a lock with a bolt engageable with a strike on the door casing in a deeply recessed mortise. A planar elongated plate, symmetrical about a vertical axis, is in the mortise. An elongated bolt opening and a pair of screw clearance holes go through the planar plate on the axis. Also in the planar plate is a pair of screw rod holes, both disposed on one side of the axis. These receive a pair of screw rods extending through the intervening space and into the cripple as cantilever beams. The usual strike plate overlies the planar plate, its bolt opening registering with the bolt opening in the plate and its screw openings substantially registering with the screw clearance holes. Screw fasteners extend through the screw clearance holes in the strike plate and through the similar holes in the planar plate to engage the door casing side rail.
