Engineered with a special focus on burglary, the FB-685 Hollon Oyster safe features heavy duty hinges and a unique 1” thick hinge side locking bar that extends from the top to the bottom of the door. With a 2 hour fire rating at 1700° FB-685 Hollon Oyster safe truly brings the best fire and burglary resistance for the price. With 2 moving front bolts and 1 vertical locking bar, the FB-685 is near impossible to break into. This Hollon Fire and Burglary Safe features an anchoring hole on the bottom of the safe, and all bolting hardware is included. By bolting the safe down, you force a burglar to crack it during the break-in, and with this safe's burglary protection, all I have to say to the burglar is: Good Luck. Hollon provides the option for an S&G Electronic Lock or S&G Spyproof Mechanical Dial for the same cost on the FB-685. Both lock options come with a glass re-locker for extra protection.
