I’m really impressed with these 12-inch Heavy Duty Floating Shelf Brackets!
Size: 12 Inch, Style: Black 6Pack
I recently installed them in my living room to hold some books and decorative items, and they’ve been fantastic. The brackets feel extremely solid and well-made — the 1/5-inch thick iron gives them a sturdy, industrial look and they hold the shelves without any wobbling or sagging. I also love the sleek black finish; it looks modern and stylish, and it really complements my décor. Installation was straightforward and stress-free because the set comes with screws, anchors, and a lever — everything I needed to get the shelves up securely. The pack of six brackets is great because it gave me enough for multiple shelves and even an extra in case I need it. The only minor thing to note is that aligning the brackets perfectly requires a bit of patience, but once leveled, they hold like a dream. Overall, these brackets are a great combination of strength, style, and value. They’ve made my shelves look clean and professional, and I feel confident they’ll last for years. Highly recommend for anyone looking for heavy-duty, attractive shelf support!

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.

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.
