Square checking fixture.

Ebay item #: 182177877834
 
It can only be used to compare. It needs to be calibrated to verify square. And the base has been sand blasted. And it has an import indicator. I think very over priced.
 
Used to compare sides. Zero on first side then rotate to next etc. No calibration needed. The bottom has been reground.
