The swing bolt is patented and designed to work with safes that have bolt work and are suitable for any security level.
It has a unique design with the tongue pivoting to allow the safe to open. The tongue has an oval pivot hole which pivots on a round pin, which is the secret to the strength of the swing bolt system.
If the bolt is forced the initial movement is to swing but once there is some resistance the bolt slides sideways and locks on a reinforced stop preventing any chance of punching the bolt.
It also allows for the lock body to be located at any point in relation to the input pad, removing the need for the lock to be fitted directly behind the keypad, which greatly improves the security of the safe. The swing bolt has few moving parts and is dual handed.
The square bolt operates by either the keypad or a knob turning to open the lock. It can be used for direct locking and is available in a number of different bolt lengths. It is suitable for all applications up to bank vaults.
The spring bolt operates by the keypad or knob providing the turning to open the lock. It is used for direct locking and if auto locking is required.
The knob operation would be favored because of the lighter action that allows the latch to spring back more easily. It is perfect for use in drug safes and cash drawers.
