GN 826 control knob flanges are normally used in connection with control knobs and smaller handwheels.
Using these flanges, spindles can be clamped gently and easily, without much construction and installation effort. The clamping wedge grips the spindle, preventing maladjustments caused by vibrations, or to keep the spindle securely in place after adjustment.
This flange can also be used to simply lock the spindle in place.
Flange may be mounted so that the clamping lever / clamping screw is positioned either on the left or the right hand side.
GN 711.1 indicator arrows can be attached to the circumference of the control knob flange.
