REINFORCED FIRE DOOR
The innovation in our Reinforced Fire Door comes from the combination of 21st century technology and time-honored thick plate steel. The outer edge of the door is precisely folded around two layers of fire board (one layer in Maverick safes) and a solid steel plate that runs the full length and width of the door. Because there are three layers of steel on the outside edge of the door, (where a prying attack would take place) Fort Knox Vaults are unmatched in strength and security.
TRIPLE RELOCKER SYSTEM
Engineering relocker systems into a door that will lock the vault mechanism when under attack is a great second line of defense. If a thief attempts to cut out the lock, the relockers drop into position and keep the door closed. Fort Knox provides you with not just one, but three or more relockers to keep your door tightly closed against the most determined attacker.
