The Hollon Safe Fire & Burglary Oyster Series is designed to resist both burglary attacks and fires. These safes have been put through a rigorous KIS and JIS 2 Hour Fire Test at 1700 degrees external and 350-degree internal temperatures as well as a 30-foot impact test.
Each safe is engineered with heavy duty vault style hinges along with a full length 1-inch-thick locking bar which extends from the top to the bottom of the door. Even after cutting the hinges off of the safe the door cannot be removed. Talk about security!
Every safe comes standard with S&G Electronic Lock or UL Listed S&G Group II mechanical dial. Each Oyster Series safe comes equipped with a glass re-locker (except on FB-450) for additional security during drilling attacks. Another feature the Oyster Series offers is a detent for automatic re-locking (with electronic lock) of your door when closing.
