The DRIFT 24-Inch Roof Rack is a must have for the kayak adventurist! The universal roof system features 2 portable roof rack pads that attach to the roof of virtually any car or van, and prevents scratching, scuffing and damage. The protective foam roof pads are lightweight, shock-absorbing and dampen vibration. The adjustable cam strap and corrosion-resistant metal buckles lay across the roof pads and can be adjusted to load sizes. Two cushioning pads are included to reduce vibration noise when the car is moving. Make certain that straps are pulled tight with no slack and your transport items are secure before transporting. Make sure the items you are transporting are completely resting on the two pads and not touching the car roof surface to prevent damage.
