4pcs 90 Degree Angle Clamps, Corner 90° Woodworking Corner Clip, Right Angle Clip Fixer, Clamp Tool with Adjustable Hand Tools (4PCS7) Rerirok

Very nice for small jobs

I had some problems to figuring how to use it ,but after watching a video of how to use it, it makes things much easier and accurate and sturdy.

I make a lot of small boxes and holding them for assembly and gluing is awkward. I tried these and they improve the process, but are not as simple as I had hoped for. I found the venter V shaped part of the clamp often sticks and makes assembly difficult. I put a tiny bit of Boshield T9 lubricant on the sliding portion of that center V and that helped considerably. I used Boshield since it dries completely and doesn't leave any residue on your wood to interfere with finishes. There are a few other corner clamps I will play with when I am in a wood working store next, but there are fine.

These seem to be very cheaply made. Poor instructions, do not slide easily. Might be good for occasional use, but doubt they will hold up for any length of time.

Bought these to help with making small planter boxes. They hold at the corners so you aren't trying to hold down making sure not to slip while screwing in your screws. These clamps not only make it easier, they make the project so much faster so we can get more done.

These clamps didn’t meet my needs. If you’re doing woodworking and want square corners these will not hold the butt joints or mitre joints flush. One side always sits proud. The clamping pressure isn’t enough to drive fasteners in without pushing your product out of square.
