ABSTRACT:
A latch bolt strike lock which has a locking plate, horizontally reciprocating, located within a door latch strike plate. When actuated by a vertically reciprocating locking actuator, the locking plate engages a rectangular bolt locking recess installed into the flat side of the reciprocating latch bolt of the door lock. Thereby forceable retraction of the latch bolt from the latch bolt hole is prevented.
