ONCE THESE ARE GONE THEY ARE GONE FOREVER!
So stock up now if you like these!
Great Price! These knobs fit like a glove on 1/4" smooth shaft pots.
The flat head set screw is set inside the plastic of the knob not a brass cup so it's super easy to strip the plastic and have a knob that does not stay on. I recommend buying a few extra in case you strip that screw!
Our heavy duty 1900 knobs do not have this problem.
Measurements are 1/2" at the base and 5/8" tall for a 1/4" shaft.
