If you replaced your Tune M1 light switch dimmer with a mini RF remote control dimmer, then you need this. This allows you to mount the cradle next to your MaxxAir remote (if you have one) so that it is easily accessible and not bouncing around in the truck bed. Screws and hammer nuts included. Made from chopped carbon fiber nylon material (https://markforged.com/materials/plastics/onyx). Will not fade, UV stable, and robust.
This is a made to order component and could take a few days to fulfill depending on the production queue.
