Mechanical Locking Systems


Chubb Isolator unit is a unique mechanical locking system that engages and disengages (isolates) for the operation of the bolt-work from the locks on Chubb high-security safes and vault doors.

PlusLockTM is an auxiliary relocking device (RLD) that is activated during an attempted burglary of an ATM safe or vault door. Even after the primary locking has been defeated, PlusLock will keep the door locked with its independent mechanism comprising a spring-loaded bolt held in check that is protected by glass re-lockers and designed to release and block either the bolt-work or the door from opening.
