UltraGroove Metal™ is a retractable tonneau that makes it easy to attach nearly any Thule® or Yakima® rack to carry bikes, kayaks, cargo baskets and more. It offers truck owners the metal look with heavy-gauge aluminum panels and a tough, powder-coated, matte-black surface. With or without racks, UltraGroove Metal is a great-looking retractable tonneau that’s incredibly easy to use. It opens quickly with just a turn of the lock knob and closes just as easily with a pull on the built-in strap. " The built-in RES™ rail expansion system can quickly be outfitted with racks to carry your recreational gear.
