Please read all notes before purchase!

The default images show a knob with a voltmeter and RPCM.

Selecting your knob: Select the options that matter to you most, because once an option is chosen the remaining options will dwindle down only to what is available. Make sure to select your color last as there is no way to unselect a color. To reset, put everything back on "Pick One". If you've already chosen a color, simply refresh the page

Please refer to our RPCM product for more information about it's use. They do require an RJ12 cable that does NOT come with the purchase of the knob. Make sure you check the box to have us include an 18ft RJ12 cable for an additional $12.99

Important Note for Clear/Frosted Knobs ONLY: The color of the cables may not be represented in the images above. Cable colors may include Blue, Green, Orange, Pink or Patriotic (Red/White/Blue). If you have a preference, enter it in the comments at checkout. We will contact you via email if what you request is unavailable and move forward from there.
