TL-30 ULI safes are equipped with: Highly efficient bolt detent system that keeps the bolts retracted when the door is opened and never fails to engage them automatically when the door is closed. Superior quality double relocker. Drill resistive hard plate. Stainless steel push plates
In order to delay any attacks, our ingenious boltwork design makes multiple attacks necessary. In fact, actually attacking and forcing one bolt will result in driving all the other locking bolts in the opposite direction and will make further attacks even harder.
