Review: Nice quality - Seems like nice quality and work well to hold carrier in place of smaller square bar mounts my car topper came with.
Review: Great value replacement - Cheap replacement hardware that doesn't totally fit our older Thule cargo box. Had to drill 4 holes to adjust fit but otherwise this item is as good or better than original equipment. Why? Has plastic coated U bolts and the tightening knobs don't have flanges sticking out. This is great since your gear don't get caught as easy. I would buy again since it cost 5-6 times less than OEM. I ordered the Thule Snap fit hardware at the same time for my box and these inexpensive mounts are better and easier to install. I cannot say enough good things about this hardware.

Good quality but did not work for our roof rack. I wish there was more specifics about individual pieces as spacing and size was an issue.
