These are not as easy as you would think to install. When mounted on the roof of a midsize car with a wide stance snowboard set-up, you have to mount the bars far apart. When they are far apart the roof is not flat and the rectangular load bars are not parallel to the roof. When adding the board rack they do not stand straight up and angle away from each other. They look silly. Yakima load bars are round and this problem would not occur.
