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.

ARCHITECTS/ENGINEERS SPECIFICATIONS
ETI sequence key retaining devices are to be integrated throughout the location or facility and are exclusive to ETI Products. The key retaining device shall be used for all key control activities which require remote or special location access by authorized personnel. The device shall be designed whereby rotational retention is activated and controlled with a sequence m echanism which uses rack & gear function for engagement of cylinders. The lock body must be of solid machined aircraft aluminum which incorporates an interlock T-Slide bracket for wall or plate mounting. Final body mounting must use concealed fasteners and/or high security fasteners specified/approved by ETI Products. Overall design will display and function with the collective features of durability, safety, anti-tamper and anti-vandal. Optional colors may be used in aiding in the identification of key control and its application for user and area control.
