Simple => versatile!
I used these simple L brackets for a different application than they were designed for -- to create "platforms" or "ledges" on which I could support gutter guards against the back of the gutter. I know, kind of random. But they worked! And they're aluminum, so they won't corrode. Only product I found on Amazon that looked like it would work for this purpose.

Easy to use and works great.
I'm using 20x20 aluminum extrusions to build and open-air case for the computer I'm putting together. These corner brackets are working great and are easy to use. Just kind of expensive so I took off a star. I would buy these again and will for my next project with extrusions.

Easy to use came as described
Bracket quality:Came straight and with all the listed hardware. I used these to help brace and square the frame on my Tronxy X5SA 400 pro and they did an amazing job would def recommend for anyone else looking to stiffen up their machine a little more.
