Hi Guys,
Can anyone give me the measurements of the black knob used on this control.
I am really after how high it is.
Thanks
Les

On my panel, the knob is two parts, black outer lower part is 10mm High and the tall inner knob protrudes 25mm above the outer knob. total height 35mm.

Thanks John and Merry Xmas.
Would you be able to tell me also what is the width of the skirt on this knob.
Thanks

Happy Christmas to you as well Les,
The Black lower knob is 18.5mm dia. with flat across it of 1.5mm (so it forms a D-shape).
The upper knob diameter is 13mm.
Hope that helps.
John

Thanks John.
