8 Pack Table Legs Foldable Hinges Lock Extension Support Bracket Foldable Self Lock Hinges for Table Legs, Bed Leg, Workbench

It works great for building a soccer rebounder for my son. It is heavy-duty and locks in place. It shows no signs of collapsing while in use.

I haven’t installed these yet, but from opening the package, these seem to be well built and sturdy. They are certainly a bit stiff at first, but already seemed to open and close a little easier after a few times, and I’m guessing they will function better once installed too, since I’ll then have more leverage.

Las compré para colocarlas en el mueble de la foto para que la cubierta bajara y subiera, el mecanismo funciona a la perfección.

To be honest, I have not used these yet as I decided to change the design of my project before these arrived, although I am certain that I will use them on another project in the near future. That being said, here's what I can tell you about these folding brackets so far. First of all, they were much smaller than I expected. I had perceived them to be about twice the size of what they actually are, but the dimensions are given in the description, so that was just my own brain assuming and the important thing is that they are the right size to work with a 2x4 or 4x4 as a leg. They are a bit difficult to open and close, but I feel that once they are mounted that they will probably operate aa smoothly as they should. These do seem to be well made and I'm pretty sure I would buy them again and once I do use these, I'm pretty sure I'm going to need more. I do think they are a great value for the price.

I like the positive strong lock, and they come with lots of screws. They are not exactly 90 degrees, and the way they are built I think it would be hard to alter that even a little. I am using the to make a folding outfeed table for my band saw.. They work great for my use.
