Abstract:

A common method to operate a door is to have a door knob on the door connected to a latch which slides through an opening in the door into another opening in the door jamb. When the door is closed the latch extends from the door through the strike plate and into the door jamb. To open the door the latch must slide away from the door jamb past the strike plate and into an opening in the door (usually accomplished by turning the door knob, pressing a lever handle or turning a key). By inserting a pin through the latch when the door is closed, the latch cannot slide away from the door jamb and the door cannot be opened.
