The DX-90 Monster Mech physically blocks the locking bars from moving once the safe is locked, even when an attacker loads them from the side.
Dual relockers can secure the safe after an attack, while the slip-clutch disconnects damaging force applied through the handle.
Three hardened steel plates shield the lock before a drill can reach the working mechanism.
A heat-activated Palusol seal expands around the door to help restrict smoke and heat.
Pro Flex shelves hook into a tracking grid at variable heights and positions, letting the interior change as the collection does.
