At Hamilton Sinkler, we're designers and manufacturers of outstanding collections of classic and contemporary door, cabinet, bath and register hardware. 

While our remarkable catalog continues to be a preferred choice of leading design professionals, we also have a prestigious bespoke service offering the realization of original custom designs that includes 3-dimensional confirmation prototyping. 

Our team of talented designers, machinists, artisans, refinishers and hand polishers from The United States and around the world accept no compromises. A truly global firm, we manufacture our exceptional hardware in the best world locations using modern state-of-the-art machining technologies combined with centuries-old traditions of handcrafted fine detailing. 

As an example, our stunning HL050MOP Art Deco-neoclassical door lever was designed in The United States, is expertly machined, refinished and hand polished in India and carefully inlaid by artisans with mother-of-pearl in The Philippines. The beautifully decorated lever motions on our superior American-made latching mechanism manufactured with the same exacting standards as with the production of a luxury watch. We’re proud that this favorite lever of America’s top interior designers and architects is as efficient, durable and as satisfying to hold as the steering wheel of a fine sports car.
