Nice brackets
These are nice sturdy brackets for butcher block shelf however they do bend a bit. We installed in a corner so was able to pin to side wall no problems on big shelf. The smaller shelf about 18” moves a bit up and down when loading. Now very little and no worries about it but not rock solid

Sturdy Shelf Brackets
I really like these shelf brackets. They seem very sturdy, which is great for my laundry room shelves over the washer & dryer pair. It's going to be great to FINALLY have shelves for laundry supplies or "buyers' club" household items like 12-packs of paper towels or 36-packs of T.P. I can hardly wait to have my sons install them so I can fill them up!

Neat and Square
Color: Black, Size: Square
This turned out to be durable and looks good on my valet table. The difference in the way it snaps to the sides, keeps the corners square and looks better than the other models that force the corners to extend outward.
