We recognize the important role played by the door product. Fortunately there is a door hardware manufacturer that shares our aesthetic and determination to have design make a difference. That is why we have partnered with FSB USA. FSB has produced door hardware for over a century. FSB's lever designs are so admired that four have been added to MoMA's permanent collection. Swing Door full mortise ANSI A Grade 1 locks are available in all standard functions, Sliding Door full mortise locks for entry and privacy doors as well as a Pocket Door full mortise lock with an integral edge pull, all with FSB's extensive selection of lever, knob and flush pull trims in various metals and finishes.
