dormakaba G-N Mechanical Hold Open Unit

The RF hold-open unit enables doors to be securely held without any fall-back at precisely the required position up to an opening angle of approx. 150°.

The hold-open function can be easily switched on and off by the user, and the release force can be adjusted to the door type concerned.

The RF mechanism is non-handed and has been specifically designed for retrofitting to the G N type standard slide channel. GN

The suitability of the hold-open unit may be limited where the closer unit is fixed to the door leaf on the push side, in combination with outward-opening doors, and also in the case of large, heavy doors.

Not for use on fire doors
