What is a Safe Deposit Lock?
Most modern safe deposit locks are actually two separate locks inside one housing that work together to control a single locking
bolt. The whole idea is to have a lock that requires two different keys before it can be unlocked. Traditionally, a single key is
used to control one side of all of the safe deposit locks in a bank. This key is maintained by the "vault custodian," and is
called the "Guard Key." The guard key is always inserted into the lock plug that is the closest to the hinge on modern locks. Once
the guard key has been turned and left in the turned position, then the key that the renter of the box controls is inserted into
the other plug and turned to unlock the box. Naturally enough, the key that the renter controls is normally referred to as the
"Renter's Key." Only when both keys are inserted and turned can the box be opened.
This safe handle Fits safes with 1/2 inch handle shaft.
