PRODUCTS > SEQUENCE LOCKS

The key retaining device is an effective tool for improving the control of keys. With a sequence key retaining device, a release key is inserted into the retaining device and rotated. The rotation will allow removal of retained key and in turn traps the release key. The release key remains trapped until the retained key is returned and rotated. After this action, the release key can be removed, with the retained key being trapped.

These sequence retaining devices establish accountability for important keys (ex: master keys, emergency bypass keys, access control, safety lockout, etc.) and dramatically reduce both human mistakes and risk exposure for higharchy level keys. This key control of put and take system acts as a mechanical sign-out sheet when active.
