Handwheels GN 228 of sheet steel or stainless sheet steel are robust and unaffected by shocks and knocks. The hub lengths l₁ and the diameter d₃ correspond to DIN 950.

The stainless steel design is suitable for applications in highly corrosive environments thanks to the A4 materials used.

On the revolving handles of type D, the O-rings minimize the radial play, protect the handle bearing from penetrating dirt and prevent noises resulting from vibration.
