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!

Excellent, solid built shelves. Comes with every type of fastener you could possibly need to install. Even comes with a small level. Very impressed with it all and highly recommend.

Nice shelf, install a bit problematic
Color: Dark Walnut, Size: 8.5inch(2PCS)
Nice little shelf, looks great, feels stable enough for my small accent lamp.
Two issues:
1. The cutout in the corner is perfect for a cord >>>BUT<<< the plug itself CANNOT fit though that hole. You have to feed the cord through BEFORE INSTALL. So once it’s in, it’s IN.
2. Install seems pretty straight forward but it was not so easy! The rails are too thick for a pencil to go through the screw hole to mark placement. I had to physically hold everything in place and leveled WHILE I drilled. Rather annoying.
