Surco J100 roof rack mounts

These 4 Surco roof rack mounts mount to the factory roof rails (the ones that are kinda triagular with a curved outer edge, not the ones that are flat with a channel in the middle). BRAND NEW, I opened one of them to look at it and then set them on a shelf. I made my own brackets instead, so I have these still.

They are 40 bucks plus tax and shipping online, so I'm asking $40 shipped, since they are brand new. Located in norcal.

Do you know if these adaptors will work with any other racks than Surco ?

I have no idea. They should, because they just create a flat top that a bolt goes through. I'm sure you could "make it fit."

Thanks for the link. I dont think they will work for my yakama, its round tube and the surco is square. thanks anyhow !!

Yakima makes these clips that allow a square clamp on a round bar, but other than that you need something else.
