Clamping Squares for Woodworking,90 Degree Corner Clamp Woodworking Tools,(12Pcs) - 3/4/6 Inch Adjustable Positioning Squares for Picture Frame,Box,Cabinets,Drawers.

Exactly what I was looking for. Perfectly square. But, they are heavy duty plastic, not metal. I have used them on a couple projects now and they don't give. Especially like the multiple sizes for different sized projects.

I have always struggled with holding things together at 90 degrees. These jigs take the guesswork out. I thought about getting the name brand aluminum versions of these clamps but I think in the future, I’ll simply re-order these.

Not good for 2x2 wood working. But 1x1 and smaller it is great. Super easy to use.

The clamps seemed sturdy enough for light duty. But they are not square. They are close, but they are not precise. In some projects they would probably be close enough and work fine. But I expect squares to be square.

I bought these for my husband. He seems to like them. Likes the way they are made and love the size of them.

Squares are very accurate and do not flex. A must-have tool for building cabinets and cabinet doors. The holes and clamps work well for holding pieces in place while drilling and do not mar the wood. Highly-recommend for any wood shop.

due to the variety of sizes as well as how these clamps work, the allow an extremely wide range of uses. Setup is a bit involved due to the amount of screwing and unscrewing required to get the clamps oriented correctly. Once setup is initially worked out however repeat operations become significantly faster.

On time and as advertised. Not a perfect solution, but they do work. For the price, great!
