I bought the double rack to use for my paddle board as i did not want to pay the £60+ for a paddle board specific rack. After taking the gamble it has paid off, i now have a multi purpose rack that i can put my surfboards and paddle board on. The racks are secure and easy to use and come in a handy bag. They fit my Warrior pickup nicely through the front windows and through the canopy windows. Would also work on vehicle without canopy. Easier for getting the boards on the roof. The D-ring is a great idea and if secured correctly will work with no hassle. Overall would highly recommend.
