Norton
Norton Door Controls offers a comprehensive line of door controls designed and manufactured to ensure superior performance and reliability. Founded in 1880 by Lewis C. Norton, Norton Door Check Company began manufacturing and marketing the first practical commercial door closers. Though cumbersome, his first door closers were effective devices which permitted the adjustment of the door's sweep speed. In later years, Norton Door Controls refined the rack and pinion closer and the concept of valve controlled backcheck for hydraulic closers. Along the way there have been a variety of other innovations, including the aluminum alloy body, narrow style, non-handed closers, adjustable backcheck, speed adjustments and special application arms. When Fire/Life Safety Standards were established, Norton introduced the 7200 Series Electromechanicals and later the Power Tracks®. In 1990, the American with Disabilities Act (ADA) was passed requiring buildings to have handicapped accessible doors for the physically challenged. This law brought about the creation of the original PowerMatic® Low Energy Operator. Today, Norton Door Controls offers traditional surface, industrial economy, overhead concealed, security, commercial, architectural, electromechanical and electrified closers. To complement the closers, Norton also offers a unique range of arms to help provide maximum door and frame protection. Since 1957, Norton Door Controls have been manufactured in Monroe, North Carolina. |
