Universal tie downs for Roam Adventure Co. Rugged Cases and Coolers. No need to run a strap over the case or drill holes through it just to keep it secure. Now, you can run any sort of ratchet, cam, or other type of strap through the slot down to a tie down and keep your cargo secure. These simply drop in the slots on the case or cooler-- it couldn't be easier. Perfect for your truck bed, trailer, or other roof rack.
