Beware they don’t look heavy on the picture but they are really heavy. Do you get value for it? Yes because they are so thick and heavy duty. Are they easy to install?

### ⭐⭐⭐⭐⭐ Sturdy
*by C***D on January 20, 2026*

These are very heavy and sturdy!! I used for floating shelves on a butcher block counter top. They came in 2 different boxes. One from USPS and in great shape. The box from UPS was in really bad shape. The driver asked me to open it before he left to make sure nothing was damaged. The color was worn off on one bracket at the edge. It wasn't going to show so I kept the order. I would reorder again. I did not let customer service know.
