Heavy Duty Granite Countertop Support Bracket 4 Pack - 12"x6"x2.5" Black Shelf L Bracket for Quartz, Wood, Concrete, Laminate Countertops

Works like a charm. Way cheaper and better quality than what you can find in the box stores. Used them to float a butcher block countertop in a large pantry.

These brackets work great. Extremely strong

Strong and modern set up

In the shadow of our freshly remodeled kitchen, there stood one final challenge: a 30-inch countertop overhang—majestic, beautiful, and ever so slightly threatening to collapse under the weight of our culinary dreams. My wife had the vision; I had the fear of gravity. Enter the Countertop Support Brackets, a quartet of ironclad saviors forged (probably) in a mountain forge by countertop paladins. With a graceful 12-inch reach and a finish that whispers elegance but screams support, these brackets transformed our floating slab of quartz into a monument of strength and style. Installing them felt like a rite of passage. Once mounted, they didn’t just hold the counter—they embraced it with unwavering loyalty, like knights guarding the edge of the kingdom (the kitchen). And the best part? They look fantastic. Sleek, minimalist, and confidently silent. They don’t shout, “Hey look, I’m doing the heavy lifting!”—they simply do it. Now our counter floats like a spellbound island in the middle of the room, drawing compliments from guests and zero creaks from the structure. My wife is happy. I am in awe. And these brackets? Eternal.

I love seeing these supports in white! I see them in black at all the box stores. The quartz I am installing has a white background and I purchased these “L” brackets for my island overhang. I feel like they will blend in much better in white. These brackets are heavy duty, meant to hold some weight. The ends are beveled, which is great considering that people will be sitting under the overhang. I couldn’t be a happier customer all around.

The worked great for my office counter . They could be a little stronger. Not meant for a lot of weight, bet very strong .

Perfect for supporting our new countertop!

I recently used these countertop support brackets for my butcher block countertop installation, and I couldn't be happier! The 16-inch heavy-duty design is perfect for providing the stability I need, so now I don't need to put any legs for support. They were incredibly easy to install, thanks to the clear instructions and included hardware. I've placed some heavy items on my countertop (including myself), and these brackets hold up exceptionally well, giving me confidence in their durability. The only drawback is that I wish the screws and bolts were a bit longer for a more secure fit, especially in thicker countertops. However, this is a minor issue considering the overall performance. If you’re looking for reliable support for quartz, granite, or wood countertops, I highly recommend this bracket set. They provide excellent stability and are a great value for the price!

These are very sturdy and hold a lot of weight. Great for an over lay in an extended counter top.
