With a Level 7 Security safe, you get thick walls made from 10-gauge (9/46-inch/3.57mm) steel. Thicker steel is always better for security and fire protection. One of the most obvious benefits is the increased weight of the safe. The weight per square foot of 10-gauge steel is 5.625 pounds. The heavier the safe, the more difficult it is for a thief to tip it over or cart it away to try and open it offsite.

The door on a Level 7 safe is made with 3/8-inch thick solid steel plate, which makes it more rigid and able to resist even the most aggressive attack. The door on the National Classic Plus gun safe is a great example of an extremely secure door. Its 2-step door with that solid steel plate is a whopping 5-inches thick! That makes it very difficult to pry open.

All Security Level 7 gun safes come equipped with Liberty’s DX-90 Monster Mech locking mechanisms. This mechanism has a strong over-center, direct-drive cam that provides superior protection against side-bolt punching attacks.

During an attack, the mechanism goes into “dead lock” mode as the over-center cam releases pressure on the locking bolt. And in attacks where a burglar attempts to torque the safe’s handle, Liberty’s patent-pending slip clutch technology causes the handle’s shaft to slip and release pressure on the lock to prevent it from breaking.

Instead of locking pins, Liberty uses 4-inch wide military-style locking bars for added security. The bars in Level 7 safes are made from 3/8-inch thick steel and are installed all 4-sides of the safes’ doors. The advantage of locking bars vs. traditional locking pins is that it makes it more difficult to pry or punch the door open.

Security Level 7 safes are equipped with ball-bearing hardplate lock guards. By embedding ball-bearings into the hardplate steel, the security for the safe’s locking mechanism is elevated to a higher level. If a burglar attempts to drill into the safe’s locking mechanism, the drill bit snaps or just keeps spinning.
