Thule U Bolt KIT for Box

This product works excellent with my GoPlus Roof Box (14 cf) and my Thule Aeroblade cross bars. The roof bar spacing on my 2016 Jeep Grand Cherokee is such that the GoPlus mounts will not fit the Aeroblades bar spacing and it was difficult to locate a T-slot adapter that would be reliable for the size of the box at any speed. These U-Bolts work perfectly to wrap around the bottom of the Aeroblades and secure on the inside of the roof box with the metal plate and clamping connectors. I'm now able to use my GoPlus Roof Box without resorting to using my older Thule square bars.

Ok so first off these are listed for a certain model of Thule, however, knowing Thule I was pretty sure the mounting holes are all universal for the company. Took the risk and ordered them for my Mountaineer. They fit perfectly fine. took me about 15 minutes to install.You may need another person to help you hold them still depending on how big your case is and if you cant reach to hold them yourself. but these solved all our issues.Thanks!!!

Does precisely what it supposed to do. The U-bolts fit through the holes and into the cargo box.An improvement Thule should make is add 1/4 inch to the U-bolt thread. But, it works okay. Sufficient thread protrusion for my liking.

I appreciated the helpful reviews prior to ordering this. This set worked perfectly for my older Thule roof box and stock Toyota Sienna roof rack bars. My roof bars are pretty thin, and this set would likely not work for very thick roof bars.I've included a bunch of pictures for what's included in the set. As you can see, it's Sportcraft brand (apparently now owned by the Thule corp.)One caveat that made me bump this set down one star- The back packaging (see pic) shows installation with U-bolt plates both outside and inside the roof box. This set includes only the narrower set of U-bolt plates, and the installation instructions included shows installation with plates only inside the box. That's a bit confusing for one, and two it would seem to make sense that having both internal and external U-bolt plates would make the mounting hold stronger and safer.I already had external U-bolt plates from a previous set that I added to this set when I mounted my box, so this hardware set fit my needs perfectly. But, if I didn't- I would order the Thule Replacement Parts Bag Hardware 05603 instead which includes 4 outer U-bolt plates as well as the 4 inner ones.

Easy to use on a variety of cross bar shapes, very secure. Well worth the cost. I didn't need all four as I had only lost one from the original set, but luckily they weren't very expensive - and these knobs are actually more comfortable than the originals, so I now use all four of the replacements.

Was a little nervous getting these after reading some reviews. They worked perfect. Have an older Thule ski carrier that was made to fit the old square bars. These bolted on fine with enough clearance to go around the new fatter bars. I did have to drill a new hole through the plastic carrier because the older brackets were so much more narrow.

I modified by drilling two additional holes in the on the rear end of the carrier in order to fit my car rack. The original hole was not far enough to reach the rear rack. By drilling the two holes and using this to secure the carrier onto the rack, we were able to use carrier for road and camping trips.
