Riverside® 16in No-Skid Kayak Block Sherpak Lock your kayak to yourExtra long foam block for kayaks that need more support. At 16 inches, the Riverside No Skid Kayak Block provides a wider contact area than standard blocks, reducing pressure points on your hull during car top transport. Non skid base grips your crossbar without shifting. Works with Riverside carrier kits and most crossbar systems. When you're hauling a longer or heavier boat, more foam means more confidence on the highway.
