Designed to help you easily get any type of kayak up on your roof, the hand roll's rubber ROLLERs provide load assist with grip, stability, and protection. The bases pivot to automatically fit the shape of your boat, then lock tight to cradle it while traveling. The universal mount fits most roof Racks - no tools needed, and heavy-duty straps and tie-downs are included to keep things secure. Add sks lock cores for added security. Sold in pairs, the hand roll can team with another set of ROLLERs or our deckhand saddles for a custom set-up.
