The 8500 is a UL Group 1 combination lock made by Sargent and Greenleaf. It is mainly used on safes and vaults.
Principles of Operation
The 8500 uses a spring mechanism to prevent the fence from touching the wheel pack during dialing. There is a U-shaped spring connecting the lever to the case. Unless the gates are aligned properly, this spring will not allow the nose to rest on the drive cam.
