The Davies 1900H knob is one of the most popular knobs for pedals, because the size is big enough to grab, but the narrow diameter doesn't suck up all the real estate on the face of the pedal. Some iterations of this knob are all plastic--even the threads. This led to stripped holes or insufficient tightening causing slippate. For that reason, we're only carrying the heavy-duty model with a threaded brass insert. Same appearance, but higher quality and no more slippage or stripped holes.
They are easy to grip, turn, and view your settings as they have a recessed indicator line, filled with a high-contrast color (see images).These come in a wide variety of colors, and they are relatively inexpensive.
Please note that these are the variant designed for 1/4 inch smooth shafts and the knobs feature a set screw to securely hold the knob in place.
The knobs are ~13mm Outer Diameter (OD) and are ~16mm tall.
These have a hex set screw, and we'll include a hex wrench with your purchase, and an extra hex wrench if you buy 25 or more knobs.
