Review on 🔒 Premium 4 PCS Stainless Steel Roof Box U-Bolt Clamps with Lock Nuts - Easy Car Van Mounting Kit, Universal Fitting Accessory, 85mm Internal Width and Durable Straps Included by John Baker

Product usable but not quality controlled. A nut was loose and did not slide easily over the U-bolt. Also, a nut will not stay in its plastic retainer and is difficult to hold in place when using a clamp. If you can't find anything better, this clip set can be used and securely attached to the roof rails of a 2016 Chrysler minivan. It's not quick to use, however, with one or two nuts (out of 8) either poorly made or tight. I use these clamps to attach a square aluminum tube rack to the crossbars. The price is reasonable if like me you are buying a lot of parts to create a product that mimics an item that cannot be purchased due to Covid supply chain shortages.
