to the right dimension
The item came in but the diameter of the metal was 3/16" and not 1/4".The tag on the item also states 1/4..

Not the correct size, but easy to make fit!
My search for a replacement stainless steel U-bolt for my antenna mast found this one. The existing U-bolt is steel & was rusting after years exposed to the elements.As my review title says, this U-bolt is too narrow at 1-1/8". I needed a 1-1/4" U-bolt, the standard antenna mast size. This is stainless steel, so there's no problems with resizing it on a piece of 1-1/4" pipe. No need to worry about any scrapes or nicks rusting on stainless steel. The resizing was very easy to do on an old piece of pipe. I Hammered the U-bolt onto the pipe, then use a vise to finalize the shape. To my surprise, the plate still fits perfectly! :)The pros:+ $6.46, which included free shipping, or $2.10 + free shipping if you get this when it's an "add-on item"!+ 300 grade Stainless steel, so it will never rust & it will last forever!+ Comes with a stainless steel plate & 2 stainless steel 1/4-20 nuts.The cons:+ Doesn't come in 1-1/4" size.I bought 3 of these & I may up the product rating to 5 stars after I install one of these U-bolts.โบ Update - August 8, 2013I installed one of these today on a 1-1/4" antenna pole & the resizing made the U-bolt a perfect fit. I've decided to up my product rating to 5 stars.โบ Update October 21, 2015I have 2 of these installed now. The first one I installed on an antenna pole, 2 years ago, still looks like new! Not wanting to be without a couple on hand, I just added another one of these on my Amazon order. I couldn't pass up the $2.10 + free shipping price!.

Just what I needed
I had a puzzle to figure out, how to connect two objects for easy removal. Not your typical use of this item. But it suited my need perfectly. Sturdy enough to rely on

Installed over salt water for 2 years... excellent
Bought a couple to install a weather station on a piling over Florida sun and salt water two years ago. Still look like new. Excellent quality.
