Sargent & Greenleaf Safe Deposit Lock, #4 Long Bolt, Right Hand

It's a handed lock, and only the right-hand version is offered under this model. Handing on safe deposit locks refers to the direction the bolt throws, so a right-hand unit will not work in a left-hand nest position. Check the box position before ordering, because a handed lock cannot be flipped in the field.

Nose height is 1/2 inch, and the nose diameter is 0.672 inch on both the renter and the guard side. Those two numbers decide whether it drops into an existing door prep, so measure the hole in the deposit box door before you pull the old lock.

It matches if the rest of the nest is running S&G #4 long bolt locks in the right-hand position with the same 0.672 inch nose diameter and 1/2 inch nose height. Safe deposit nests are usually built out with one lock model throughout, so the fastest check is to remove the failed unit and compare nose diameter, nose height, bolt length, and handing against this spec.

No. The renter key is retained in the lock while it is unlocked, so the customer cannot walk away with the key and leave the box open. It releases only when the box is relocked. That's the behavior branch staff expect on a standard two-key nest.

It uses a pick-resistant lever design that resists advanced decoding techniques, and it meets UL Standard 437. Lever locks of this type are the norm in bank deposit nests because both the guard and renter keys must be turned before the bolt moves.

Bolt length is what matches the lock to the depth of the box door and the strike in the nest frame. This is the #4 long bolt configuration; if your existing locks throw a shorter bolt, the long bolt will not seat correctly and you want the matching short bolt version instead. Pull one existing lock and compare bolt projection before you order a batch.

Safe deposit locks are ordered as the lock body with its guard and renter key interface; keying and key sets are specified separately by the institution because renter keys are changed per box and guard keys are held by the branch. Confirm your guard key requirement with your key control program when you place the order.
