Lcn 4642-689 Complete Aluminum Door Closer

Product Description

The LCN 4642-689 is a complete aluminum door closer designed for commercial door applications. Door closers in this series control the speed and latching action of a door, returning it to the closed position after each use. The 4642-689 ships as a complete unit, meaning all necessary mounting hardware and components are included. This type of closer is typically installed by commercial door hardware specialists or general contractors working on commercial or institutional facilities.

The 4642-689 is suited for commercial interior and exterior door installations where controlled closing speed and reliable return action are required. The aluminum construction makes it appropriate for environments where corrosion resistance and a clean finished appearance are priorities. Finish code 689 indicates an aluminum finish, consistent with the base material.
