You get two of these in each box. You will need to order two sets. If you are hauling two kayaks or two boards. Be aware that the profile of the clamps on these "J-bar Racks" are for a crossbar that is more round or square in shape versus flat and oval as are my crossbars on my Rav4. They would clamp real well on a crossbar that was 1-1-1/2 inch round or square.
