Our access interlocks have two parts: a main body (with one or more cylinders) and a latching block or bolt. The key is always held whenever the two parts are separated; only when the latching block or bolt re-engages the main body will the key be able to turn and be removed.


Our interlocks mount directly on your standard equipment. Choose the mounting option that best fits your application; adapter plates and locking bolt modifications are available here [link to accessories]. Contact us if you feel you have a non-standard mounting situation or if you need the locking bolt modified in any way (e.g. a hole in the end of the locking bolt so a fixture can be attached).
