Fort Knox Defender Gun Safes & Vaults

Taking a Protector Vault and adding the durability of a thick Zolatone finish creates a practical vault designed for the rough shop type environment. Fort Knox Defender -- the best value for a conservative budget.

Fort Knox Defender Vaults have been tested by Underwriters Laboratories and have been granted a Residential Security Container (RSC) burglary rating. They have been independently tested and carry a certification for 90 minute fire protection at temperatures up to 1650 degrees F. The reinforced fire door is now standard on all models.

  • The 1/4-inch thick steel door and the many high-end security features on these safes — including the Sargent and Greenleaf Group II manipulation resistant lock, the clutch drive handle and the FOIL™ mechanical backup re-locking device — offer a tough barrier against burglary.
  • The uni-body construction of the Defender Series gives you a 1 1/2-inch total body thickness.
  • The interior is fully lined, including the back panel on the door, with a durable carpet which is velcro friendly. This allows you to apply velcro holsters directly to the walls and doors to hold your handguns.
  • On the Defender Series of these Fort Knox Vaults, the dead bolts (bolts that do not move) have been replaced with active bolts that actually retract into the door to allow it open. These active bolts are located on both sides and the top and the bottom of the door. There are up to thirteen 1 1/2-inch diameter locking bolts on each safe.
