Abstract
Disclosed herein is a redundant boltwork mechanism comprises a master lock plate and a sublock plate slidably coupled to the master lock plate. A first lock is coupled to the mater lock plate and a second lock is coupled to the sublock plate. A cross slide with a plurality of bolts and at least one other slide are coupled to the safe door such that turning that handle of the safe door causes movement of the cross slide and at least one other slide from a first position to a second position, allowing the safe door to be opened. The safe door can be unlocked by unlocking either the first lock or the second lock, which causes the second lock tongue to retract from blocking the at least one slide.
