I've put it through the wringer

Great rack system. Exactly what I needed to get my rack setup. If you are unsure on what you need for a rack check out and enter your car into the fitkit tool or give us a call!

Works like it should

I've used it several times

These did exactly what they are supposed to. Used mine with the raised tower system as well. They did not disappoint

If you have round bars you need these. Don't forget. I used mine with the Yakima TimberLine Raised Rail Tower System. Does come with new end caps to put in the round bar.
