Cheap easy surfboard rack!
These will fit great on Yakima or Thule bars, or even some "smaller" factory bars. I had them on my old Pathfinder bars, which were maybe 3" wide. The pads won't go all the way around wide bars, but you really only want to cover the top of the bar anyway, so you can just tie them on below, and they are fine. I use these pads, along with a set of tie-downs, to transport surfboards. Super cheap & easy way to move boards, boats, or anything else. Giving your rack the cushioning of these pads makes it much more universal, everyone should have at least one set!
