Control Knob 19mm with Movable Pointer Cap for 4mm Round Shaft K21 R40S

This is one item of new mixer / radio volume control knob which has a removable coloured cap with an indication line. One item is the knob and the cap. This listing is for the smaller 4.0mm round shaft fitting type. This has a fixing screw in the side which can be tightened using a standard 2mm flat screwdriver.

I try to keep all the different cap colours in stock, something which you may not find elsewhere.

Dimensions:

Height: 19mm
Skirt Diameter: 19mm
Top Diameter: 15mm
Cap Outer Dia: 13.2mm
Cap Inner Dia: 9.2mm

Five different shaft fittings are available in total, four on other listings.
