Question: Are the product dimensions correct? Listed as 8.8 x 6.8 x 10.5 inches....not possible!
Document: I bought a box of 10 last year for $50 and just ordered 6 more. They are very strong by design having the curved support made of round bar. The angle is 3/4" x 1/8" steel. Similar brackets are $7.50 plus tax at Home Depot.
You'll need a long thin screwdriver to get at the screws around where it makes its 90 degree angle with the wall. Hopefully you knew this when you bought it.
These are  very sturdy. I bought it to hold up a breakfast bar I am building and it leaves lots of knee room and works great.
The brackets were not as strong as I had hoped they would be. I was going to use them to support a granite slab, but decided to use a bracket that would carry more weight. I will however use these brackets, where strength to support a substantial weight is not required.
Nice and simple
I use these to support 9" shelves that have books on them, so I can attest to their strength (they're mounted on studs, of course). In person, they don't look at all chunky or clunky, but are quite graceful. And the best part - for me, anyway - is that they were easy to paint; I didn't even have to treat or sand the surface to get a nice, even finish.
I have two of these graceful and elegant supports holding up a shelf in my family room. The design goes with any decor and is easy to mount on the wall. The only drawback is you'll have to procure screws and screw anchors (if needed). I can recommend them for functionality and beauty.
I built shelves with them to display my aerospace and plane models. See pictures above.
I bought these because I needed a lot of clearance in the area of the bracket and I was intrigued by the design with the curved support bar. However, once you get these in your hand you see they are kind of flimsy. That curved bar is very flimsy too. In addition, the angle is not exactly 90 degrees. These may look nice for decorative purposes but they will not hold much. I would not purchase these again.
