Our door closer portfolio offers you a variety of different modules. Door closers as slide channel door closers with rods, invisibly integrated in the door frame or the floor. With a fail-safe function that enables almost resistance-free opening of fire doors and for barrier-free construction inside and outdoors. The smoke detectors with integrated power pack and the RM-N smoke detector perfectly complement the proven, practical dormakaba hold-open systems for preventative fire protection. Our door closers close doors up to 1,600 mm wide. For this, the closing force and speed, among other things, can be individually adjusted.
