It's designed to clamp onto your vehicle's existing factory or aftermarket roof crossbars (round, square, or aerodynamic). The J-shaped cradles are padded with thick foam to protect your boat's hull, and they feature large adjustment knobs so you can angle them to perfectly fit different boat shapes and sizes. The best part? The J-arms FOLD DOWN flat when not in use, so you can park in your garage without having to remove the whole rack. It includes heavy-duty ratchet straps with S-hooks to securely lash down your boat, and suggestions for bow/stern tie-downs for extra security on the highway. Installation is straightforward. A solid, versatile, and space-saving transport solution for any paddler.
