Product description

Five-lobed control knobs EN 5338 are very appealing with a nice gripping feel. The manufacturing technique has made it possible to produce them with no visible flash mark.

The pointer element is pressed into a groove on the hand knob hub which secures it from twisting.

Two socket set screws with serrated points ensure a secure attachment to the shaft.
