great for saris hitch racks these are awesome more heavy duty than i expected i give it a 4 stars because of the price does its job for a cost works great with my hitch mount storage basket good 85 effective dont expect it to make it 100 rigid best out there has worked great for us no more rattling this was just what i needed to keep my bike serves its purpose very well tightened worked well for couple days then loosened up and very good to use when using a cargo carrier or bike hated it great product
