Norton 7705PTO-24V Support Unit Pull Side Power Track Electromechanical Closer-Holder

The Norton 7705PTO Power Track® Closer-Holders combine the functions of a single point electromechanical door holder with the proven reliability of a 7700 Series Door Closer. The track assembly contains an arm slide and solenoid operated hold open mechanism and is available without an integral smoke detector. The closer is mounted on the door. The Power Track and hook-up box are mounted to the frame face for pull side installations. The Power Track is an aluminum extrusion which incorporates a solenoid actuated cam that locks the arm slide in the track at a selected point. The degree of door hold open is selected by adjustment of the telescoping arm. When there is power to the unit, the door will hold open at the selected hold open point. Any power interruption will release the arm slide and the door will close. The door can be released manually at any time.
