Fits perfectly on trailer bumper

I used these to bolt a channel tool box to the rear bumper of our Thriller. I had to trim the thread to fit, but this feature works great.

Pros
  • . If plates are required use National #2191 plates
Cons
  • Update Availability

You don't have to buy these records. They come with U-bolts.

Very confusing. Purchasing the U-bolt does not imply that the plates are included. So I went ahead and bought them. Been to U-Bolts! So I'm giving it back.

Pros
  • For attaching various products to rectangular wooden and metal objects
Cons
  • Empty

Good solid U-bolt.

Exactly what I was looking for. Used with U-shape plate to fix flagpole to RV bumper. There are no problems with rust, it is very strong. The mast did not give way in very strong winds. Looks as good now as it did then.

Pros
  • Nuts included
Cons
  • Discontinued model

VERY POOR QUALITY - Bare Thread

Threading was bad on 2 of the 4 I had. Couldn't even undo the screws that were on them. Threads were bad in several places. Since I. need to complete this project i will pull out my faucet and fix them instead of having to worry about returning them through amazon so the buyer should be wary of dealing with these poor quality parts.

Pros
  • For attaching various products to rectangular wooden and metal objects; 3/8"x4"x7"
Cons
  • Quality

Fit my purpose

I used it to attach an air hose reel to a garage ceiling. The hose reel is heavy and I was concerned that the clamp bolts that came with the hose reel might one day come loose. I put the U-bolt on the rafter and through the hose reel hanger, problem solved.

Pros
  • Good product for the price
Cons
  • weak

Good parts but not stainless steel

Decent parts. Ok my standard 4 inch trailer bumper - that's what I'm going to use for the attachment. These are regular steel with a "weatherproof" zinc coating to help them resist rust. They are definitely NOT stainless steel (although the description incorrectly says it is stainless steel). .revain should really fix the listing).

Pros
  • Quality construction
Cons
  • Requires outlet

VERY POOR QUALITY - Broken threads

Threads were bad on 2 of the 4 I've had. Couldn't even undo the screws that were on them. The themes were bad in several places. Since I have this project to complete, I'm going to pull out my faucet and fix them instead of having to worry about returning them through Amazon. So the buyer should beware of dealing with these poor quality parts.

Pros
  • Few competitors
Cons
  • unreliable
