3-point locking is a locking system installed in cabinet or locker doors to enable more secure locking. Whereas in single-point locking, the door on a cabinet locks only at the point where the key is turned, halfway up the edge of the door, three-point locking enables the top and bottom of the door to be simultaneously secured.
