To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The clamps worked perfectly for my truck rack. I applied them to the Xtreme US Pick-Up Adjustable Rack and my 2013 Ram 1500 4x4. The rack was purchased on Amazon as well. The main use for the rack and clamps, hauling two kayaks. Highly recommended both products.
Works very well, lower profile than others I have a sleeping platform inside my truck topper and theses are out of the way better than my old ones! I strongly suggest putting “anti-seize” type material on the bolt threads prior to assembly. Steel bolt tightened into aluminum will gall and cause damage to the clamp without it.
I ordered these as an alternative to Tracrac over the rail clamps. I needed more clearance for tonneau cover brackets. These did the trick. They line up perfect with the groove in the foot of the upright. Great find.
Online purchases often disappoint. Anything that can be made cheaper and lighter will be, and it will be marked "heavy duty". These clamps are nice and beefy. The finish is excellent, and the thread depth is good, about 1/2 inch deep on a 7/16 bolt. A great bargain, not expensive.
Used these clamps to hold my home made truck rack made of 2X4s and closet shelf supports from Home Depot. The clamps hold the rack tighter than a drum. Way more than satisfied especially for a price compatible to C clamps.
