The channel stop (or track stop) is what you’d use to keep your cargo rack, roof rack, or luggage rack from going up to high. You can install this anywhere on the lift channel to keep the racks mentioned above from going too far up.

Tabb Buel (CEO and founder) gives us a brief explanation of how this works. It’s a pretty straightforward install. You’d use a ¾” wrench with the ½” bolt that comes with it. You put it in the track. Twist it tight. Done.
