Fort Knox Executive Gun Safes start with what few other safe companies even offer, a 1/4″ (4ga) steel body. That’s what makes the Executive series the first safe of Fort Knox’s heavy-duty line. While most manufacturers will stop at a 3/16″ steel body, Fort Knox safe takes your security to the next level. That body thickness combined with their Reinforced Fire Door with full plate steel reinforcement, Fort Knox safes patented Rack and Pinion 5-to-1 reduction gear drive, and 90 minute fire rating at 1680°F place the Fort Knox Executive gun safes series above most other competitors’ top of the line safes. When you’re looking for more protection than a typical high-end safe offers, the Executive is the place to start looking. With many sizes to offer, Executive gun safes come in the Executive 6031, 6637, 7241, 7251 and 7261 sizes. One of these sizes should be perfect for you safe needs. As with all of their safes, the Fort Knox Executive Gun Safes are proudly made in the United States and boast the most comprehensive lifetime warranty.
