The Type ZKNU-3 is a fluted type knob with skirt diameter of 1-5/16". It accepts both 3/8" and 1/4" shafts using a supplied bushing. It is constructed of black phenolic resin and has a "spinner" attached. The spinner is useful when a slow motion dial is encountered. See the photo below of the Type 722-ME.
