The Surf’n Gear 18″ Regular Rack Pads are the perfect length for surfboards and are sized to fit crossbars with a 1″ to 1 ½” diameter which includes the Yakima round bar, the Thule basic square bar and narrower factory installed racks. Made with a “Fade Proof” Acrylic, these rugged rack pads are offered in three great colors and feature an innovative Velcro closure tab that runs the full length of the pad to assure a solid fit that won’t wear out like the smaller Velcro tabs found on other rack pads.
