Boxer EFS 4-6

GEZE Boxer EFS 4-6


Integrated free swing door closer with comfort hold-open function

NEW: Integrated free swing door closer GEZE BOXER EFS with comfort hold-open function and adjustable closing force EN 4-6

The new Boxer EFS size EN 4-6 for single-leaf doors provides the perfect combination of the new, integrated comfort hold-open function, which allows the door to be stopped at the end of its free swing area, and the tried-and-tested GEZE "free swing" function.

Locking the comfort hold-open function prevents unintentional closing, for example in the event of a draught, at the maximum opening angle. This has no effect whatsoever on the fire protection function – when this is triggered the door always closes safely, even when the hold-open function is engaged.

Furthermore, the "free swing" function enables people to go through the door almost without any physical effort, in the opening or closing direction, once the door has been opened once, e.g. in the morning. This makes it ideal, for example, for use in retirement homes or hospitals.
