Rim Lock is about a locking device for a door. Most rim locks used today on exterior doors in india are latches. Rim locks and rim latches are often used on wooden doors. A rim lock may also be seen on an antique pantry, pie safe, and other cabinets. Some rim lock and latch sets have a shallower backset than does a modern bored cylindrical lock or mortise lock, allowing their use on doors with narrow rails.
