Sturdy and sleek

These brackets are exactly what I needed for my garage shelving. The black finish matches my tools perfectly, and they feel incredibly solid once mounted.

Solid construction

Heavy duty iron support as described. The coating seems durable and hasn't scratched during installation. Took off one star only because the packaging was slightly damaged upon arrival, though the product was fine.

Exceeded expectations

I used these to repair a broken corner on a wooden workbench. They are much stronger than the original hardware. Very happy with this purchase.

Easy installation

The pre-drilled holes lined up perfectly. I was able to install four shelves in under an hour. Highly recommend for DIY projects.

Great value

Very good quality for the price. The screws provided were a bit short for my thick oak boards, so I had to buy longer ones, but the brackets themselves are excellent.

Perfect for floating shelves

Installed these in my living room for some heavy bookshelves. They hold the weight without any sagging. The matte black looks modern and clean.

5 FAQ

Q: Do I need to buy screws separately?

A: No, each package includes matching black screws and wall anchors suitable for standard drywall installation.

Q: Is the black finish prone to chipping?

A: The matte black powder coating is baked on for durability. While no finish is completely chip-proof, it is significantly more resistant to wear than standard paint.

Q: What is the exact thickness of the metal?

A: The brackets are manufactured with a thickness of 2.5 mm to ensure high load-bearing capacity without being overly bulky.

Q: Are these brackets suitable for outdoor use?

A: Yes, made from 304 stainless steel with a powder-coated finish, they are resistant to rust and suitable for both indoor and outdoor environments.

Q: Can these support a granite countertop?

A: While very strong, these are designed for shelving and light furniture. For heavy materials like granite, we recommend consulting a structural engineer or using specialized heavy-duty supports.
