Information

GN 439 levelling feet are used for installing smaller machines, systems or devices.

Thanks to the rubber underlay, they have a damping, noise-reducing effect and prevent surface damage. They are also designed such that the threaded spindle can absorb compressive forces. This is necessary because the retaining washer is not evenly supported during leveling.

Thanks to the stable rivet connection between the threaded spindle and the retaining washer, the introduced forces can be reliably transmitted to the rubber underlay.
