The Master Series is Superior’s best-selling safe. This masterpiece has it all–the right combination of security, fire protection, style and enduring value. The Master’s first line of defense is its body and door construction. Its 3/16" steel body, with Double-Steel Door Casement™, is almost 8 times stronger than the lightweight 14-gauge box store safes. The body is pressure formed with a 5/8″ corner radius bend, increasing strength and providing distinctive styling. Its Double-Step™ door contains 3/8″ of steel thickness, 3/16″ outer steel plus a 12-gauge inner steel plate. The door edge is increased to 3/4″ using multi-layer reinforcements. The door is approximately 38 times stronger than the lightweight China- built containers. (see Steel Strength chart) The Master Series provides state-of-the-art door defense systems including: NEW Glass Relocker, full inner door steel, Cam-Lock™ pressure reliever, Diamond-Embedded Armor Plate™ lock protection and a mechanical relocking system. In addition to its heavy steel construction, the Master has four-way active boltworks, with 1-1/2″ diameter door bolts. Its fire rating is unsurpassed in its class at 1750° for 2-Hours. Its mirror-like exterior finish and full velour interior adds a lasting touch of class. Besides the attractive style and finish, the Master Series provides a heavy steel foundation–a foundation that will provide years of security.
