A fader knob of a Pioneer DJ mixer consists of three small parts: the DAC2684, DAC2685 and the DNK5888. The Pioneer DAC2685 refers to the white edge of the knob.
The Pioneer DNK5888 is the Slider Knob Stopper that snaps the knob firmly onto the fader. Should you want to replace the entire fader, you will need the Pioneer DAC2684 and DAC2685 in addition to the DNK5888.
