IS315 - Sliding arm door closer (force 3-5)

The IS315 sliding arm door closer is the ideal overhead door closer for the majority of doors on the market today (in wood, metal, aluminium etc.) and may even be installed on fire-resistant doors. The closing force of the closer is adjustable from 3 to 5 with a setting screw. Equipped with an adjustable backcheck to prevent the door from being opened too rapidly, the door closer may also be equipped with an adjustable hold open device or limit stay. Boasting a silent closing action, the door closer also has a delayed closing action which facilitates use by disabled or elderly persons and allows bulky objects to be carried more easily through the door. Unique, stylish design, with a casing enclosing the entire unit concealing and protecting all the adjustment valves.
