Inside clamping dimensions on the Mega Squares

[Tool_Chuck]

I weld a lot of 1"x 2" tubing using butt joints in corners. I align them so that they are lying flat on their 2" side and then the 1" side is welded to the end of the other tube. I hope this makes since. I need to know the dimensions of the inside clamping area of the Mega Squares so I can choose the smallest square that will still have an adequate reference area to clamp to.

I’m too old to just buy “the BIGGEST” anymore.

My original Monster Square (Cast iron), as great as it is, has been getting a bit heavy lately.

Thank Jason for the quick reply. In the picture are the dimensions I needed. I’m looking for outside corner support.
