Security is Liberty’s Number One Priority.

Liberty has a Safe Security Level designation for each safe we manufacture. This 8-level system allows you to easily compare the different security features.

Good Security

Security Levels: 1,2,3


  • I just need basic protection and to keep children away from firearms.
  • Items inside the safe are easily replaceable.
  • Someone is home most of the time.

Better Security

Security Levels: 4,5,6


  • I need increased security against crime and smash and grab burglars.
  • Items inside the safe are valuable and covered by home owner's insurance.
  • There are long hours during the day when nobody is home.

Best Security

Security Levels: 7,8


  • I need the highest security levels available.
  • Items inside the safe are of high value, irreplaceable and have significant sentimental value.
  • There are times when I am away from home for extended periods of time.

Security Level Side-by-Side Comparison

Steel Thickness

Steel Gauge Thickness chart

Your safe’s door and walls are its first line of defense in keeping crooks out. The thicker the steel, the better security protection your safe will provide.


The measurement system for steel can be a little confusing. A lower gauge of steel is thicker than a higher gauge.


Door Construction

Two components that have a major impact on a safe’s security level are its door and locking mechanism.

Composite Door Construction Differences

The locking mechanism in your safe plays an important part in its level of security. It needs to keep the door locked if a burglar smashes or removes the safe’s lock, tries to torque the safe’s handle or attempts a side-bolt punch attack.

Safe Mechanism Level differences

All Liberty locking mechanisms come standard with our patent-pending slip-clutch feature for added security protection. If a burglar attempts to torque your safe’s handle, its shaft will slip and release pressure on the lock to prevent it from breaking.

New Locking Bars

Why are locking bars better? 


Locking bars are 4 inches wide and six times stronger than round pins found in other safes. They provide a larger surface that resists prying and punching because they go deeper into the safe when locked in place. They are also made from one, solid piece of American-made steel.


Standard round locking bolts are individually and permanently riveted to security brackets before being installed into a safe door. While they have been the industry standard and are effective, they are not as efficient as Liberty’s military-style locking bars.

Lock Guards

We protect our locks and locking mechanisms withhardplate lock guards. These strong plates of hardened steel are great at thwarting drill attacks because they quickly chew up, snap or spin the drill bit.


Multiple layers of hardplate will chew up a drill bit quickly as it continues to shake, trying to get through the steel’s hard surface.


Ball-bearing hardplate is even tougher on a burglar’s drill bit. Numerous ball-bearings are encased into a piece of hardplate. When the crook tries to drill into your lock, either his drill bit is going to snap, or it will keep spinning on those tiny steel bearings forever.
