The Malone Downloader Duo Kayak Rack is an all-in-one kit to store up to two kayaks vertically on top of your vehicle. The package comes with 2 sets of Downloader racks, two sets of JAWZ universal mounting hardware, four Malone 12-foot cam buckle straps with protective covers on the buckles, and two sets of Malone's SpeedLine ratchet style tie downs. Making frequent trips with your kayak is made easy with the fold down carrier frames that have a locking mechanism that when unlocked allows them to lay flat on the roof when not in use. This is a huge time saver for those who would normally need to attach and detach their racks when entering garages with lower clearance. On top of all that, loading your kayak is made easier with the help of the built in loading ramps. This product also carries Malone's trusted limited lifetime warranty.
