There's a reason that Yakima calls them "Universal" MightyMounts. These little marvels let you fit just about any Yakima accessory to your factory roof rack bars. A set of them is mighty nice to have. Soft, grippy Dynaflex™ pads protect your crossbars and hold the Mighty Mounts firmly in place. Universal design lets you move your racks and accessories from vehicle to vehicle with no hassle. Sold in a set of four, no tools required for assembly. The Accessory Lock Housings and SKS Lock Cores add additional security (sold separately).
