High quality look for office
Size: 10 Inch, Style: Black 4Pack, Size: 10 Inch, Style: Black 4Pack
These brackets were exactly what I was looking for. Very solid construction, clean powder-coated finish, and they gave the shelves a modern industrial look without being bulky. Installation was straightforward, and once mounted into studs they felt extremely sturdy.
I used them for floating wood shelves and was honestly impressed with how much weight they can handle without flexing. The black finish also matched perfectly with the rest of the room hardware.
For the price, these are a great value and look far more expensive than they are. Would definitely buy again for future projects.

Heavy duty brackets!
Size: 12 Inch, Style: Black 6Pack
Super heavy duty brackets. Slim look and hardware pack included is good quality. Comes with two kinds of anchors and matching screws. Bought multiple sets and very pleased with them. Paid 30 bucks for a 6 pack.

These shelf brackets come with screws and are easily installed. Very sturdy and can hold 14 hardcover books easily. Would recommend these shelf brackets for use to hold things to the wall.

Needs heavier duty wall anchors
Size: 10 Inch, Style: Black 6Pack
Brackets are nice and sturdy and look great in my son’s room. The included mounting hardware is not strong enough to support the brackets and shelves and I had to purchase heavier duty wall anchors, other than that great product.

Very sturdy.
Size: 12 Inch, Style: Black 8Pack
Great buy compared to similar product at Home Depot. Screws can be made of a better quality metal. Overall very sturdy. Fits 2x12 lumber great.
