Door latches are a type of mechanical device used to hold doors shut. Like all latches, those specific to doors use a fastener to join two surfaces together while allowing for their ordinary separation. Latches work in conjunction with, but are not traditionally the mechanism that actually locks the door. In the past, bolts have been used solely to lock. Recently, however, latches have emerged that are able to both lock and fasten a door or other object. There are several different kinds of latch designs that can be used on doors.
