Fabulous! I’ve purchased these more than once!
Size: 12 Inch, Color: Gold, Size: 12 Inch, Color: Gold
These are beautiful and the perfect size for the 12” wide boards I use. The lumber isn’t cut to exactly 12” so there is a slight gap in the back towards the wall which I like for cords, and the boards stay in place with bottom screws. These are very sturdy, thick, and solid. I have not had a single problem with any of them. They are easy to install and very functional. Definitely worth the cost. I have purchased a couple of times.
