90 Degrees Right Angle Clamp 3in Corner Clamp Picture Holder Woodworking Holder(Pack of 4)

Had to return these. metal was warped on some and they also twisted and warped while trying to clamp materials. Very cheap design, needs thicker metal and better quality control in manufacturing. I would not use these for anything thicker than 1/4" to 1" picture framing.

I am returning these because the threads cut into the wood since they sit up above the surface of the clamp.My other complaints are that the moving part of the clamp is up sits above the body too high so it pivots all over.The crank is way too small to be practical as well. The crank is only 1-5/8" long next to the 1-1/8" width of the clamp body, giving you only 1/2" overhang to use as you tighten the clamp. The crank should be at minimum twice that long.

just too low on the part that holds the wood. Should be 1 inch higher.When on the bench with wood in clamps the bars to tighten are too small and very hard to turn because they hit the surface when turned.

Light use only on small picture frames. One clamp came bent and while gently straightening it it broke. I straightened it and added an aluminum scab to the break with liquid nails. I would recommend this product only if it’s being used for light weight frame assembly.

These seem to do the job just fine. I do wish the riser was a little taller but I was able to pretty easily square up the corners of an L-Shaped shooting table made of 2x4's. Didnt have enough for the whole table at once so I migrated these around when setting the screws and had no issues with square or level.

You get what you pay for. Not very sturdy, but works well for light work

Cheap... Bends as you tighten..

These are junk. Do not waste your money.
