Series 31

double entry, Zinc alloy cam lock.
10 disc Tumbler mechanism  




The Series 31 is a robust Disc Tumbler mechanism for high-volume applications requiring heavy duty keys and minimal security.

The strong keys are designed to withstand heavy usage and are easy to insert, due to the reversible double-sided key design. The Series 31 also has a 'positive-click' locking and unlocking action to prevent the locking cam from falling back under its own weight if keys are left in the lock.

Accessories and keys
The Series 31 can be supplied with a choice of two fixing methods: a brass body nut or a horseshoe clip. A wide range of compatible cams are available to order in addition to our locking systems. Special cams are also available to order, subject to order quantity.
