    Great for bookshelves!
    Size: 9.25 INCH
    Heavy duty and super sturdy. The brackets feel solid and well made, and once installed they hold shelves very securely. Great quality and exactly what I was looking for for an industrial-style shelf setup.

    Great feel and quality, will buy again
    Size: 5.5 INCH
    These are gorgeous! The thick, heavy look and feel that I was hoping for, great screws to match (we used different anchors, since the provided anchors are not the strongest style). Similar ones at the local big-name hardware store are at least three times the price and are no better quality. I would (and will) definitely buy these again for more projects. Originally bought the six of these even though I only needed two because the price was still the best I could find, and ended up using all six almost immediately. They look so good, I found more projects for them!

    Nice looking. A bit too much flexibility. Did the job.
    Size: 11.25 INCH, Size: 11.25 INCH
    We made use of these shelving brackets in our kitchen remodel. They turned out great. We used 2x12 Douglas Fur boards that were sanded and painted to show contrast with the brackets. The brackets installed easy enough with a level, tape measure, pencil, and a drill for pilot holes. Other reviewers are correct: the mounting screws that come with it are essentially junk. I had read this and ordered black wood screws ahead of time with the hopes of returning them. I used the 1" screws to secure the shelving to the brackets. The 2-1/2" screws get to go back as we were able to use the included screws to secure the brackets to the wall. But, two of the first three heads on the 1" screws popped off... so, we quickly moved away from those included. There is a little more flex in the brackets than I had expected... they're just a little too thin for 11-1/2" shelves. It won't affect anything for us as we'll just be placing dry food and canned goods on them in our pantry. But, if I were using them for the garage or the shop I'd probably buy a different brand OR decrease the space between brackets. I spaced mine out 12" from each edge and then 12" on center. Works well for our pantry.
