Worked as intended
Hubby used these to mount a shelf above a long span of windows. They worked great and allowed a clean visual appearance.

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!
