The Crown safe is Omega Certified for 2.5 hours at 1550^o F. The Presidential safe's 1" thick HiSecurity composite door and 2" insulated body provide a defensive barrier against theft and fire. All Champion Safes come standard with a Sargent and Greenleaf Group II lock, providing the smoothest action and security available. Champion's Glass Relocker provides additional security protection. If the lock is tampered with the Glass Relocker completely locks up the safe.
