Ridged Fluted Control Knob with Raised Position Indicator
This control knob features deep ridged flutes running vertically along its circumference, providing exceptional grip and tactile feedback during operation. The raised ridged line position indicator extends from the top surface down the side, offering clear visual reference for precise positioning.
The knob's substantial construction and pronounced fluting make it particularly well-suited for applications requiring frequent adjustment or operation in challenging conditions where grip security is paramount. Its robust design ensures reliable performance in professional audio equipment, laboratory instruments, and industrial control panels where precise control and durability are essential.

Hole Type

Splined Hole
Knobs designed for splined shafts have holes with multiple grooves or ridges that correspond to the splines on the shaft. This splined hole creates a very tight and secure fit, preventing any movement between the knob and the shaft.
The position indicator can be placed in any of 18 different directions, in increments of 20°
The ridged interior of the hole ensures a strong connection, capable of handling high torque and frequent adjustments without the risk of slippage.
A control knob with a splined hole will not fit onto a round or D typ shaft.
