ARC-51N
Overhead Concealed Door Closer
Designed to provide a controlled closing of single or double action aluminium doors. Features include dual closing speeds to allow flexibility in its closing action, three levels of spring tension, 90° hold-open facility and a comprehensive fixing pack including a fixing channel. Specially designed arms are available to suit anti-finger trap aluminium sections. A heavy duty bottom pivot is supplied as standard.

The ARC-51N is also now available 'springless', making fabrication of a free swinging door possible without changing the standard section preparation. Click here to download the Technical Update PDF.
