Solid construction

Very rigid brackets. The only reason for 4 stars is that the included screws were a bit short for my thick oak boards, but I used my own.

Sleek modern look

Used these for a floating desk project. The matte black coating is smooth and scratch-resistant. Highly recommend for DIY furniture projects.

Perfect for my garage shelves

These brackets are incredibly sturdy. The black finish looks professional and matches my tools perfectly. Installation was straightforward with pre-drilled holes.

Excellent value for money

Bought these to reinforce a wooden workbench. They hold up remarkably well under heavy loads. No signs of rust after a few months in the workshop.

Great quality, slightly heavy

The steel is thick and feels very durable. They are a bit heavier than expected, which is good for stability but requires strong wall anchors.

5 FAQ

Q: What is the maximum weight each bracket can support?

A: When properly installed into studs or solid wood, each bracket can safely support up to 150 lbs (68 kg), depending on the shelf material and installation method.

Q: Are the mounting screws included in the package suitable for drywall?

A: The included screws are designed for wood-to-wood or wood-to-stud connections. For drywall installation, we recommend using appropriate wall anchors separately.

Q: Can these be used outdoors without rusting?

A: Yes, since they are made of 304 stainless steel with a powder-coated finish, they offer excellent resistance to rust and weather elements.

Q: Is the black coating prone to chipping during drilling?

A: The powder coat is quite durable. However, if you need to drill additional holes, we suggest using a metal drill bit at low speed to minimize chipping.

Q: What is the thickness of the steel used in these brackets?

A: The brackets are made from 2.5mm thick 304 stainless steel, ensuring high durability and load-bearing capacity.
