2800ST 689 Norton Door Closers and Operator

The cam action design is ideal as it provides greater efficiency than a rack and pinion door closer for slide track applications. Cam action closers provide a lower opening resistance while delivering optimum closing force and control. The door closer's wide range of adjustable closing power permits use in the most demanding situations.
