The Supreme Series–its elegance is only surpassed by its security. Sculpted classic lines, recessed door and radiused corners provide classic steel work second to none. The Supreme’s body is pressure formed from 7-Gauge American-made carbon steel offering 16 times the steel strength of the lightweight imported safes. Its Double-Steel Door Casement™ quadruples the strength of its door opening. Its massive Double-Step™ door offers real security. The door contains 1/4″ solid outer and full 10-gauge inner. The door provides 126 times the strength of the China- built safe doors. (see our Steel Strength chart) The Supreme’s door features a radial gear-driven bolt work with unsurpassed smoothness and strength. It operates a four-way active bolt work with strong inner door components and bolt carriages. Door defense systems include full inner door steel, Superior’s Glass Guard™ relocking system, mechanical re-lockers and Diamond-Embedded Armor Plate™. The Supreme’s heavy body and massive steel door with triple fire seals contribute to its 1750°, two-hour fire rating which is unsurpassed in the industry.
