With our mortise locksets and tubular latchsets, FSB USA introduces North America to a wide range of European designed lever handles. FSB has produced door hardware for over a century, and is now one of the leading International architectural hardware manufacturers. FSB's lever designs are so admired that four have been added to MoMA's permanent collection. Now FSB USA has successfully combined European design with American lock technology. We offer our locksets with over thirty standard levers, in both stainless steel and anodized aluminum, reasonably priced for mid-to-large size commercial projects. FSB mortise locksets are supplied with a US manufactured, ANSI standard (Grade One) UL listed (3 Hour) mortise lock or a UL listed (3 Hour) tube latch.
