## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked Great
*by P***O on January 6, 2025*

Surprisingly none of the big box stores carried these. Good quality.

### ⭐⭐⭐⭐⭐ Pricey, for good quality
*by F***N on November 9, 2023*

Needed specialty U-bolts and found them. Turned out expensive but with little choice went ahead. Received promptly, well packaged that did not fall apart and inside the needed U-bolts...

### ⭐⭐⭐⭐⭐ Good Attachment to 4x4 Post
*by N***G on April 11, 2022*

The 4" x 6 1/2" U Bolt is a good option for hanging something from a 4x4 (really 3.5" x 3.5") horizontal, outdoor post. I ordered 4 and they were all complete with 2 nuts each. Easy to adjust too, without tools. This will hold the hanging baskets without the need to damage the wood.
