GN 957 control knobs are primarily used with position indicators. These control knobs offer a simple solution when the application requires manual fine adjustment.
The design of this knob adapts it to the diameter of the adjustment shaft, so that no mounting adaptor is needed inside the position indicator to connect both items to the adjusting shaft on the machine.
