This means that the safe can withstand fires of up to 1850 degree F for 2 hours.  The safe is also built to protect its contents from heavy impacts, even a 30-foot drop, say, from the second floor. Such is  the impressive strength and safety these safes provide.

AMSEC UL3918 Impact Safe is built with added barriers and features for burglary protection. An impressive 3 ½” thick recessed food has a ⅝” thick front. This protects the safe from any prying or sledgehammer attacks. The locking mechanism is handle activated and has multiple ⅞“ diameter solid steel locking bolts with chrome finish. 

AMSEC UL3918 Safe allows locking with a U.L listed Group II key changeable combination lock with relock. This lock has a potential 1 million possible combinations, which ensures failure on random attempts by any miscreant. The relock device, which is auxiliary spring loaded, activates itself on severe attacks.
