Great quality metal

I was worried about rust since I'm using these in a humid basement, but the 304 stainless steel is legit. No signs of corrosion after three months. Highly recommend.

Best value for money

Compared to local hardware stores, the price here is unbeatable for this quality. The edges are smooth so I didn't have to file anything down before installation.

Perfect for garage shelving

These brackets are incredibly sturdy. I used them to reinforce my heavy-duty garage shelves and they hold up perfectly without any bending. The stainless steel finish looks clean too.

Exactly as described

Bought these for a custom desk build. The 90-degree angle is precise, making assembly easy. They blend in well with the industrial look I was going for.

Solid but pre-drill holes

The metal is thick and strong, which is great. Just make sure you pre-drill your holes because the steel is hard enough that screws might strip if you force them. Overall very happy.

Good support brackets

They work well for what I needed. Took off one star only because the package didn't include mounting screws, but that was mentioned in the description so my fault for missing it.

5 FAQ

Q: Is this suitable for supporting a granite countertop corner?

A: While strong, we recommend consulting a structural engineer for granite supports. These are best suited for wood shelving, framing, and general light-to-medium duty reinforcement.

Q: What is the thickness of the steel?

A: The brackets are made from 2mm thick 304 stainless steel, providing excellent rigidity for most shelf applications.

Q: What are the exact dimensions of the bracket arms?

A: Each arm of the L-bracket measures 3 inches in length and 1 inch in width. Please check the product images for a detailed dimension diagram.

Q: Can these be used outdoors?

A: Yes, since they are made of 304 stainless steel, they are highly resistant to rust and suitable for outdoor use in most weather conditions.

Q: Are mounting screws included in the package?

A: No, mounting screws are not included. We recommend using #8 or #10 wood screws depending on your specific load requirements.
