The Fixed J Style Kayak Carrier is designed to transport your kayak or canoe on the side to save space allowing for a second watercraft to be mounted on the other side of your roof racks dependent on the length of your crossbars. The space saving design enables you to mount other accessories such as a luggage carrier for extra gear and a multi purpose holder for your paddles. The Universal fitment allows the S510 to be compatible with all current roof rack systems with specific fitting kits. Whether you're out paddling by yourself or with others, the S510 Fixed J Style Kayak Carrier has you covered so you can enjoy the most out of your day. The S510 comes most assembled out of the box with all the necessary accessories to get you started including: stainless steel hardware, rubber tube padding and tie down straps.
