Strikes (AKA door strike plates) are a type of metal door hardware installed in a door jamb to receive the corresponding bolt or latch that is installed on the door. The extension of the bolt or latch from the door into the strike holds the door closed. Strike types include lockset, deadbolt, ball catch, and others. Strikes are available in a variety of metals, colors, finishes, and other attributes. Electric strikes work with remote access control devices or digital keypads to eliminate the need for keys.
