90-Degree Right Angle Clamp, Onidoor Set of 4 Multi Angle Clamp, Picture Photo Frame Corner Holder, Woodworking DIY Hand Tools

Definitely not built for heavy duty work. I tightened one of the clamps too hard and the washer popped off the rod (see pic). I managed to get it back on but now I know not to use too much pressure or it will happen again. Great for light duty work though!

The washers at opposite end of the handle came off with light pressure applied.

They do what they were made to do.

Does the job perfectly

Arrived fast matches description. Good buy.

I bought these same ones at a hardware store. They are not 90 degrees. I don't know how they could possible work for anything important.

Worked pretty good for my project but one broke within a few weeks. The other three are still good though.
