I grabbed these as a beefed‑up replacement for the flimsy L‑brackets I put in my laundry room years ago, and they’re exactly what I needed. These are proper heavy‑gauge triangular gusset brackets with clean mounting holes on both sides. Once they’re bolted in, that shelf isn’t going anywhere.I’m using them to stiffen up the shelves over our washer and dryer. With all the laundry stuff piled on, I wanted something with real backbone. The triangular design spreads the load way better than a standard L‑brace, and the 150‑lb rating per pair is legit. You can feel the strength in the steel.They come powder‑coated white, so they match the laundry room without needing paint. Edges are smooth, holes are clean, and the spacing lines up with standard wood panels. Screws aren’t included, but I always use my own stainless hardware anyway.If you’re reinforcing an existing shelf or building a new one, these brackets are a solid upgrade. Strong, clean-looking, and built to last.

Installation was straightforward, and once tightened everything felt much more stable.The size is practical for a variety of projects, from floating shelves to cabinets and tables. Having four brackets in the pack was enough to complete my project.Overall, these are well-made, heavy-duty corner brackets that are easy to install and provide reliable support. I'd definitely use them again for future woodworking projects.

Nice corner brackets. I grabbed these for a cheap chicken coop we got that is a little flimsy at the corners when we move it - these were perfect to throw a few small screws in and help make the corners more rigid.Quality is good and these are very sturdy - not just cheap super thin metal.

Got these to help build a catio window box using 1x2 lumber. As I’m on an upper floor, I wanted to be absolutely sure that the box is secure and won’t break, both for the safety of the cats and of people below. That includes using an old heavy duty air conditioner support bracket underneath it which ensures it can’t fall, and these brackets on the outer corners. I put them on the outsides of the corners, where they both reinforce the corners and keep them perfectly square. The box is extremely stiff and can’t twist side to side. The polyester powder coat is welcome since the catio is exposed to the elements like sun and rain, and I won’t have to worry about rust for quite a while. Powder coat is more durable than simple paint. Too bad it doesn’t include screws, but luckily, I have a bag of stainless steel screws that are fit for the job.

Review of StickNGo Corner Brackets Heavy Duty Metal Triangle Supports, 4 pack white:SUMMARY: These triangular brackets are well made. The high carbon steel means these are incredibly rigid. There is zero flex. The white color paint job doubles as a weather sealant, allowing these brackets to resist rusting. These brackets are heavy duty, flawless, and worthy of a perfect 5 star rating. I'd definitely recommend this product.UNBOXING: Inside the box are 4 brackets ONLY. There was NO mounting hardware, no instructions nor any literature (pic1).IMPRESSIONS: I ordered the white color, 4-pack variant of these corner brace brackets.The quality of these 4 brackets is very good. I could not find any defects in the workmanship.The powder baked paint job is equally good. These brackets are not made from stainless steel. Instead, it used a high carbon steel which makes these stronger but also less flexible. It also lacks the rust proof property of stainless steel. The white paint job doubles as a sealant, protecting these brackets from rust.FITMENT: The 2 flat "working sides" measure 3.5 inches long. The hypotenuse measures 5¼" inches (pic2). The 3 holes in each side are spaced exactly 1.5 inches apart (pic3). The width of each side is 1" inch exactly (pic4). Lastly, the gauge (thickness of the metal) is exactly 2 millimeters (pic5).The last thing you should know about the design is that there is a single oval hole on the brace side (last pic).FINAL THOUGHTS: I would definitely recommend this product. I plan to get more of these brackets for future DIY projects. This is a flawless product with zero negatives. It deserves 5 stars.

These heavy-duty metal corner brackets from StickNGo are incredibly sturdy, sleek, and perfect for stabilizing floating shelves and furniture. I recently used this four-pack of black triangle supports to secure a pair of heavy wooden floating shelves in my living room, and they did not disappoint. The solid metal construction feels exceptionally durable, easily holding up a significant amount of weight without a single hint of bending or bowing. The low-profile black finish looks clean and modern, blending in beautifully with the wood for a highly professional aesthetic. They are incredibly easy to install and immediately eliminated any wobble in my shelves, making them an excellent choice for reinforcing cabinets, drawers, or tables as well. If you need reliable, heavy-duty hardware that gets the job done right, this set is worth every penny.
