Deadwood Crafted Tools 3D Wood Corner Clamp Kit, 4pc - 4in Steel 90 Degree Corner Clamps for Woodworking

These are not the highest quality or heaviest material but they are square and get the job done. Good for the price.

I like the strong smooth finish, the outside squareness is pretty good, but inside squareness is off slightly. If you use these in clamping inside corners, it should be okay. But using these squares from their inside angle will not be true. I would of thought DTC would have checked and machined the inside angle more precisely to match the outside angle.

I got this for solvent welding acrylic sheets together. These worked perfectly for that. the angles were tru 90 degrees, and the curves on the corners (inherently there from bending thick metal to make these parts) allowed for a gap so my solvent didnt touch these corner brackets. These are very sturdy and will not bend with your bare hands or from clamping materials together such as 1/4" or 1/2" thick acrylic.

Not 90 degrees. Returned. Thanks for wasting my time

Well built and nice finish that cleans up easy. Allows building of perfectly square wood frames. Use currently for fixing exterior window trim. Makes squaring up easy.

Very sturdy and right on

When I received my order, I only received a 2-pack of the squares - NOT a 4-pack. Amazon.com placed a replacement order for me, and when I received that one, it was ALSO only a 2-pack!! :( Luckily, I had convinced Amazon to let me keep the first 2-pack rather than return it to them, because otherwise I'd still be sitting here with only a 2-pack! Lots of runaround and extra work just to receive what you paid for..

I ordered and paid for 2 pair of 3D Corner Positioning Square. I received only one pair. Enough said.
