Effortlessly transport stand-up paddleboards and surfboards with the Yakima SUPPup Surf Rack. The rack's universal attachment system is compatible with Yakima's round and aero crossbars, as well as most factory and square crossbars. The sliding adjuster fits two boards up to 36-inches wide. Stow-away strap management prevents loud flapping at highway speeds when it's not in use. Fully assembled out of the box, it installs in approximately ten minutes. This surf rack includes two SUPPup racks, four bolt caps, and one tie-down strap.
