Not square. I've tried a number of 'known' good squares and this one is about 1/32" longer. I won't bother getting a replacement. Will go with another brand. Hey Starrett, can you say quality control? iGaging based on reviews. No luck here either. It was "square" but an inch was NOT an inch from the end of the rule. Next go back and get another MFG. Ordered from PEC and spent some more. It's in everyone Accurate and smooth as glass, that's the way it should be.
