Fairly thick metal. All holes pre-drilled.

great to have a supplier on line

used on a flimsy cabinet for decent wheels to work.did the job. I bolstered up the cabinet with 50 other screws too.

We needed these for a recessed window that inexplicably was built by Ryan Homes with some kind of very flexy and flimsy thin plastic or fiberboard framing wall where the recessed blinds would need to mount. These worked perfectly to attach to the reinforce the corner so the blinds could be installed without pulling things apart.They would be useful for all sorts of things like this where a corner lacks strength, but needs it.

Worked great for greenhouse door

We used these to reinforce the legs on the crappy living space's chairs we bought (made with super cheap and weak wood). It's not a perfect solution, but it worked better than having to reconstruct the original corner brackets (which proved to be a more difficult task than we'd hoped) or buy new chairs altogether.

Strong like bull.

Three of the five screw holes on each bracket lie directly under the cross brace, so you need to insert screws canted at somewhere between15 to 30 degrees from perpendicular to the base, depending on the hole location and the diameter of your screwdriver or drill chuck.
