Great Quality, Nice addition to the tool collection

Works Perfectly.
I don’t use it often, but when I do it is a game changer. Really helps me with set ups and keeping everything square.

Keeps Things Square
Used this to build a backyard shed. My only suggestion for product improvement is to manufacture the clamping screws using either brass or high grade stainless steel. The screws showed signs of rust after they were left out over night and it rained.

Very handy in glue ups.
Just a very handy addition to the work bench when doing glue ups. The only downside is the slippery surfaces, friction tape would be a good modification.

Perfect 90*
You don’t need a $200 square to check the 90* accuracy of these or any other positioning/clamping squares.A simple 4 test observation procedure will determine their precision.Position one square inside the other and look for offset gaps.Swap one square from inside to outside and observe.Flip one square and repeat above procedures.Both of my positioning squares are a true 90* inside and out.Only downside is that there is not a slot in the center for adjustable positioning on a cnc. But, I knew that from the picture.

The clamps are too short and move around while trying to attach
I have a background in industrial design. The threaded 1/4 clamps need a longer return on the right angle so you can push the clamp further down inside what you are clamping rather than just on its edge. There are any situations where you need to place the clamp further inside rather than just on the edge of a piece of plywood. These won’t work for that. Add another inch or two? I ended up using these with regular clamps because they clamps they come with aren’t strong enough or deep enough. They also slip and move around because the red metal clamp has friction with the tightening mechanism. That’s a poor design when trying to hold things together and its causing things to move.
