The Dorint 770 EN 2-4 door closer with hold-open arm is designed to control the automatic closing of interior doors in commercial or residential settings, accommodating doors up to 1100 mm wide and 80 kg.
The closer mounts onto the door or door frame. When the door opens, an internal pinion-and-rack system stores energy. As you release the door, this energy controls its smooth return until fully closed or holds it open when needed via the integrated stop arm. Closing speed and latching can be adjusted independently.
