Disc handwheels GN520.1 are renowned in particular for the matte passivated aluminum ring in the front. The tough, reinforced black plastic (Duroplast PF) and high gloss polished surface give the disc handwheels a touch of elegance. The ergonomic handle is easy to grasp and makes the disc handwheels easier to use.
