The Rockies premium-level gun safes are built with a 3/16-inch steel body and a 1/2-inch steel door supported with heavy-duty hinges for long life and smooth operation. Door security comes via a three-way active boltwork with ten to twelve 1 1/2-inch locking bolts. A drill-resistant hardplate protects both the lock and secondary relocker for additional security. Integrated two-hour fire protection provides owners with an overall door thickness of 2 1/8 inches and an overall body thickness of 2 3/8 inches. With residential applications the focus, the Rockies safes utilize four pre-cut anchor holes to facilitate easy and secure installation in the home.
