Product description
Control knobs with adjustable spindle GN 727 allow precise adjustment or alignment, for example of a positive stop.
The spindle thread is without backlash.
The marking on the conrtol knob is non-abrasive and clearly legible, due to a laser engraving process which results in a very nice contrast between the aluminum-colored markings and the black anodized surface.
The same effect is also achieved on matte chrome-plated body surfaces, with the laser producing non-abrasive black markings.
Regarding design, numbering position and numbering sequence of the scale please see the layout for scale rings on the order form “How to Order Graduations”.
