Dual Key Bolt Interlock Both keys trapped( not included)

A dual key bolt interlock in a key exchange version, used as part of an interlocking system or to lock on or off electrical equipment e.g. high voltage compartments etc.



The key trapping is divided into 3 categories depending on how the keys can be removed.


Main group picture of single access bolt and dual bolt primary B secondary C full body access .

For full body access example MDBLE14-AB shown in lower picture, the primary key A , taken from the machine isolator (MRPSE11-0A) is inserted into the lock. The secondary key B may then be removed to unlock the door and the maintenance technician keeps the B key in his pocket to prevent a restart of the machine and to prevent him being locked in the area.


For lower risk partial body access situations such as a small hatch into a machine where the technician cannot be trapped inside an area, the 440T-MDSLE10-?? could be used. In this situation the secondary key is not removable once the primary key is in place.


Featuring all stainless steel interlocking and coded parts, including coded barrel & internal components. Other key code options can be supplied upon request.
