The Garvin Industries crossbar kit comes complete with four mounting brackets that attach to the sides of any 4”H Garvin Wilderness rack with ¾” square tubing. The kit also includes two Yakima compatible crossbars that are 58”L with a 1 1/8” diameter. With this kit installed, you can attach any of the mounts Yakima offers, such as bike mounts, ski mounts, or kayak mounts. This kit is also great for attaching a roof top tent to our roof rack. The clamps along the side of the rack are adjustable to accommodate whatever you are mounting to the rack. The crossbar kit includes all mounting hardware and is powder coated for durability.
