The Knob Stop is precision machined out of a solid piece of steel and is designed to keep your settings in the right spot. As you tension down the ball plunger set screw with your fingers, the Knob Stop can be locked down completely or can be tensioned so that the knob clicks firmly into place. If you are tired of your settings getting kicked and moved, you should try out the Knob Stop.
*Knob Stop's L-bracket is .30" in diameter which fits mosts standard pots. Please measure before ordering.
