This nickel-plated brass adapter sleeve converts a 0.125 in. (3.17mm) shaft potentiometer to ¼" shaft (6.35mm), allowing for ¼" knobs to be used on a wider range of potentiometers. The cutout on the sleeve allows the set screw of the knob to secure directly to the shaft of the pot. Depending on the knob used, a longer set screw can be required.
