  • Durability and practicality emphasize the quality and ruggedness of the Fort Knox Defender 6637 Gun Safe.

    Cranking up the heat to 1680°, the Fort Knox Defender 6637 is certified for 90 minutes of inferno fire protection. This is accomplished with the 1-3/4" reinforced fire door consisting of a 3/8" steel plate, 2 layers of C-rated fire board and 10-gauge steel reinforcement. Add in the heat activated Palusol dual thermal door seal and your vault will be locked, sealed and ready to block the worst that flames have to offer.

    When it comes to security, the Fort Knox Defender 6637 is UL listed due to its 10 gauge, uni-body construction, remote relocker system, drill deflector bolt guard, EasyGlide concealed ball-bearing hinges and patented multi-gear drive, 5 to 1 reduction rack & pinion locking mechanism with up to 55 rack and pinion machined gears. Combine all of that security with (11) 1.5" active solid steel locking bolts strategically placed at the sides, top and bottom of the door and you have a vault that is extremely difficult to get into, even when you know what you're doing.

    On the door of the Fort Knox Defender 6637 lies a S&G Group II manipulation resistant lock, spy-proof & key lock dial protected by a drill stop hard plate with recessed multi-bearings. After you dial in the correct combination, you'll turn the 5 spoke clutch drive handle available in gold, chrome or black chrome and see the beautiful two tone interior All sides of the safe consist of velcro compatible carpeting for additional storage room.

    In terms of functionality, the internal power supply system will allow you to plug in your dehumidifier and other various electronics. While the door is open the bolt detent system will keep the bolts secured inside the door until the door is securely closed. New for 2020, Fort Knox now includes a door panel organizer on the Defender 6637 gun safe.

    Fort Knox believes in and stands behind the quality and workmanship of the Defender 6637 gun safe by offering a comprehensive lifetime factory warranty.
