We take pride in producing the Untouchable. They are hand-built one at a time by our best craftsmen using only the finest American-made materials. It is our strongest, most secure safe. Not only has it earned the UL Residential Security Container (RSC) certification, it also exceeds the safe industries more substantial B requirements. The Class B safe is a major upgrade in protection offered by a RSC safe. A Class B high security safe must have a 1/2″ thick solid steel door and 1/4″ thick solid steel walls on all five sides. At the Untouchable’s core is a heavy steel foundation that can resist hours of forcible attack by skilled criminals. The body is formed from 1/4″ carbon steel plate with double MIG welded top and bottom caps. The massive Triple-Step™ door contains 5/8″ of steel, 1/2″ solid outer steel and 10-gauge full inner steel. The Untouchable provides over 37 times the body strength and over 300 times the door strength of the lightweight 2 mm or 14-gauge safes.
