Corbin Russwin DC62940-ET Electromechanical Closer-Holder, Push Side Mounted Support Unit. Non-Handed. 

Corbin Russwin Electric Track Closer-Holders combines the functions of a single-point electromechanical door holder with the DC6200 door closer. The track assembly contains an arm slide and solenoid-operated hold open mechanism. The closer is mounted on the door. The track is mounted to the frame face for pull side installations or the frame soffit for push side installations.

The track is an aluminum extrusion that incorporates a solenoid-actuated cam that locks the arm slide in the track at a selected point. The degree of the door hold open is selected by adjustment of the telescoping arm. When there is the 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.

Corbin Russwin electric track Closer-Holders are available in two basic functions for controlling fire/smoke doors.
