"Transport smaller, lightweight kayaks using the Malone Paddle Gear Standard SUP Foam Block Kit. Two 12"" nonskid laminate EVA closed-cell foam blocks provide a cushioned barrier between the kayak and your vehicle's roof to secure the kayak and prevent damage. The kayak blocks feature V-shaped cutouts to fit over round, square, and factory-oval cross rails. A heavy-duty, 15"" load strap secures the kayak to the vehicle. 2 tie-down lines with S-hooks secure the bow and stern. A convenient carrying case holds the complete kit for easy storage and transport.Manufacturer model #: MPG174.
