Fort Knox design the USA made Protector to stand on the more economically priced side of their lineup, but even with economical price tag, the Protector still provides plenty of great features and options to satisfy nearly anyone. This safe comes with tons of different sizing and capacity choices so you can really nail down the exact size that best fits your home and collection. There are 7 different sized models of the Protector series ranging from a small 10 cu. Ft. safe that has just enough room for a few long-guns all the way up to a massive 69 cu. Ft. options that is capable of storing more than 80 long-guns. The interior also comes with your choice of 8 different layout configurations to fit your safes specific purpose. Now that we’ve briefly covered the storage options that are available for the Protector, let’s take a look at some of the features that comes with this safe.

Even though the Protector is part of the more affordable line from Fort Knox, it still comes standard with 90 minutes of fire protection at 1680°F. You’ll find that a fire protection rating that high is common only among the higher end safes from other brands. Ft Knox uses UL listed fireboard on all six sides of the safe as well as a Palusol heat expanding seal that expands 7 times it’s size when exposed to high amounts of heat protecting your goods from heat and smoke damage. Make sure you check out my article on fire protection to get some great advice on how to choose how much fire protection you actually need.

The Protector series comes with some great standard security features as well as a lot of great optional upgrades for additional security. This safe includes a reinforced fire door, a quadrafold doorframe and a 7ga. Steel unibody construction. If you like the Protector but want a little more security, you can add the star corner bolts, an inner steel liner or stainless steel package. Even without these upgrades, most people find that the standard security features of the Protector are enough for their situation. This model is also UL listed for security and has a drill deflector bolt guard, remote relocker, bolt detent, mechanical relocking devices and a manipulation resistant lock.

One our favorite things about purchasing a Fort Knox safe is the ability to customize the interior and exterior to your exact liking. The exterior comes in 18 different color options and 2 different texture types along with 2 different interior fabric choices. Another thing unique to Fort Knox is the option to choose out of a few different Ft Knox logo designs and artwork. For an additional charge you can add a lighting package, dehumidifier, door rack, electronic keypad lock and several more cool accessories.

The Protector comes with the Fort Knox comprehensive lifetime warranty, which covers your safe from fire damage, flood damage, break-in attempts and manufactures defects. It also covers the mechanical and lock portion of your safe, which is very uncommon.
