When closed, strike drops down into lock.  This is a very reasonably priced lock, as such locking mechanism is average, not as smooth as European made locks, yet is serviceable. Made in Asia If replacing a lock: the backset measurement must be determined If you have original lock: measure distance between top edge of lock to lock pin in center of keyhole. This measurement is known as the backset. If old lock not available, determine backset by measuring: distance from center of keyhole (where lock pin will be) to top edge of drawer or side edge of door.
