Abstract:

A striker plate attached to the door frame or door jamb associated with a door provided with a dead bolt lock of the type having vertically reciprocating bolts received in aligned apertures in a pair of lugs attached to the strike plate. In the present invention, the strike plate is provided with lugs having a larger than normal area and which project inwardly of the body of the lock and have a second pair of aligned apertures for receiving a security pin so that when the security pin is in position, the door cannot be opened even if the lock bolts are retracted.
