A very nice silver aluminium knob (plastic core, aluminium shell), approx 30mm (29.5 mm) wide, 17mm high.
Standard 6mm round shaft size.
You can fit ribbed type shafts or D type. Using a D type shaft you might need to knock back the ribs in the hole slightly (just use a drill bit with your fingers, or even a screw driver's blade) to make the fit a bit easier otherwise it's pretty tight.
Very nice appearance, and the mid-size diameter makes it good for course or, or fine tuning. If you want to do more of a jog type dialing then you might want to check my other listings for the 40mm knob.
