Missing nut
Good quality though I wish they would spin the nuts on all the way when shipping. It was missing one when I got the 4 clamps I bought.

Be careful about how much pressure you add
This is my fault as I was using it to hold a lot of weight (That's why I wanted to give it a fair score) The plate bent quite easily though, just something to keep in mind.

Works as a u bolt should

These u-bolts have worked great.
As long as the correct size is ordered these should work on all of you lighter needs. If you want heavy duty then up the diameter from 1/4" to 3/8" or even 1/2" like you see in automotive shackles.

Missing parts! Otherwise functional.
One of the nuts was missing. Now I'll have to go to the hardware store to buy a replacement.
