Norton Door Controls / ASSA ABLOY
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 that 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 door closers. Other innovations include aluminum alloy body, narrow style non-handed closers, adjustable backcheck, speed adjustments and special application arms.
Today Norton® offers traditional surface, industrial economy, overhead concealed, commercial and architectural grade closers. To complement the closers, Norton also offers a unique range of arms to help provide maximum door and frame protection. Product lines include:
- Mechanical door closers and accessories
- Electromechanical door closers
- Low energy door operators
