These are a great choice!

I recently used the 4 Pack 90 Degree Gusseted Fittings for a project, and they worked perfectly for reinforcing my connections. Made from durable carbon steel, these brackets feel solid and secure. The 4-hole design provides a strong right-angle connection, making it ideal for heavy-duty applications. The gusseted structure adds extra stability, and the size (4" x 4" x 1-1.5") fits 1-5/8" channels perfectly. They were easy to install and provided excellent support for my setup. If you're looking for reliable and sturdy corner brace fasteners, these are a great choice for structural work or other projects.

These corner fittings are exactly what I needed to build a sturdy stand for an outdoor sink—because apparently every garden that gets enthusiastically planned but mysteriously abandoned still deserves a fully equipped washing station. The fittings are well made, fit together perfectly, and made the whole project surprisingly easy. The finished stand is rock solid, which is good because it now supports a sink that's used far more often by me cleaning muddy tools than by the person who originally requested it. At this point, these fittings are carrying not just the weight of the sink, but the weight of my optimistic belief that the garden will make a comeback someday. Great product, easy to use, and strong enough to support both the project and my fading expectations.

These are a lot heavier than I expected, which is a good thing for this type of hardware. The steel feels substantial, and I didn't notice any rough edges or poorly cut holes.The slots give you a little room for adjustment before tightening everything down, which made lining things up easier than if they had been fixed holes.The gussets add a good amount of rigidity, so they don't feel like they're going to flex under load.Not sure how much I trust the "galvanized" claim, but we'll see.I haven't had them installed long enough to comment on long-term durability, but my first impression is positive. They seem well made and should work well for channel framing or any project that needs a solid 90-degree bracket.

Thick, heavy duty, braces, great for welding

[Number of Items: 4]
these right angle braces are very heavy duty. Steel thickness is 5 mm or about 0.200 inches. Each brace weighs over a quarter of a pound. The corner has been welded in place for extra rigidity. Weld is clean and strong. They come with a bright galvanized coating to prevent rust. they can be used either for bolt in applications or welding braces. The price point is excellent, about half the price of welding, accessories materials that you find online. I like these a lot and I recommend them.
