Flame Resistant—Flame-resistant safes are tested to Korean Industrial Standards for keeping documents intact during a fire. An aluminum-concrete insulation in the walls blocks heat for at least two hours. It keeps the temperature inside the safe below 350° F, so papers don’t ignite. These safes are drop-tested from 30 ft. to make sure they’ll protect your valuables even if the building collapses. They’ll also shield contents from sprinklers and fire hoses, but they may leak if submerged in water.

High Security—High-security safes can be trusted with your most valuable items, including cash. They have a relocker that jams the bolts if someone tampers with the lock. Even if the lock is disabled, the door will stay shut until a locksmith opens it. These safes also shield contents from sprinklers and fire hoses, but they may leak if submerged in water.

Mounting Fasteners Included—Safes that include mounting fasteners can be bolted to the floor.
