The surface mounted closer is the most widely used closer. It gets hung on the surface of the door or frame on either side of the door. Our large selection of surface closers provides a versatility that will work in most applications.
Founded in 1880 by Lewis C. Norton, Norton Door Check Company began manufacturing and marketing the first practical commercial door closers in Boston. Through long trials designing a door closer that used air pressure, he developed a design that made doors close quietly. Though cumbersome, his first door closers effectively permitted the adjustment of the door's sweep speed. By 1900, he had developed a door closer that used liquid (hydraulic fluid) to help control the movement of the door.
In later years, Norton Door Controls refined the rack and pinion closer and the concept of valve controlled backcheck for hydraulic door closers. Along the way there have been a variety of other innovations, including the introduction of an aluminum alloy closer body, the development of narrow style, non-handed closers, adjustable backcheck, speed adjustments and special application arms to make just about any special installation possible.
