Roof Box U-Bolt Clamps/Roof Rack Clamps car Truck Universal Stainless Steel U Brackets Installation Accessory 85mm Inside Width, with 8 Lock Nuts, 2 Straps Cargo Box mounting Bracket (4PCS)

These are great! Works like it suppose fit perfectly! Quality is great too , thanks

Many components for a better adjustment

Worked great to attach a roof box someone sold me without the hardware, to the roof of my Honda. Fit perfectly except that I had to drill some extra holes on the box but it had nothing to do with the shape or size of this hardware. Quick and easy to install.. and still holding after a year of use. Well worth what I spent.

Not the best out there, but definitely not the worst, worth the money if you need something. Feel like they could be constructed a bit better, the plastic piece feels like it will wear or crack overtime in the elements. BUT worked for what I needed it to.

I had to mount a Yakima RocketBox to a Jeep roof rack. I had to do some configuring, but I got them to work. I think there is still some customization I want to do to make the mounting perfect, but that has nothing to do with this product. The clamps did their job very well. The parts are sturdy.
