4PCS 90 Degree Aluminium Alloy Positioning Squares, 4.7" x 4.7" Right Angle Clamps Woodworking Carpenter Tool, Corner Clamping Square for Picture Frames Squares Assemble Cabinets Drawers, Blue

I am sure that most people on this page are looking at these because they are some of the lowest cost options for the Aluminum 90 degree squares. I have these along with some of the other ones, and the biggest difference is the thickness of the square. These are about half as thick as the other ones I bought on Amazon. This may or may not be an issue for what you need to use them for, just note, that is why they are cheaper than other options, it is almost like they took one of the other squares and hit it in half.I did find that the edges were a little sharper than other similar products. Not to the point of cutting you, but it is noticeable.For me, I am using it for some jigs, where I do not need the thickness as much, so it is not a problem. Beyond the thickness they seem perfectly fine, they line up exactly with my other ones, so the accuracy seems as good as anything else sold on Amazon in this price range. I do not have any of the expensive Woodpecker ones to compare it against.Enjoy.

These are a great value for using them to corner clamp 90 degree wood working projects.

Exactly what I needed for small wooden boxes.

Perfect for ensuring exact angles.

The slots are great for adding clamps or for hold downs. These won't break when you knock them off the table. Smooth finish doesn't marr your pre-finish. Nice tools.A tool that will last and can be handed down to the next craftsman.

These look great, but are small.

It’s very good quality for my needs

Very handy to use. I could use a larger set now. They save time and help make accurate cuts.
