A: Level accuracy of +/- 0.0015in/in. (0.15 mm/m) accuracy is the tolerance between what is measure and the level and so is straightness tolerance is the distance between the lines leveled.
A: Super question, Russ. I had to go out to the garage and look for myself. It does NOT have measurements on both sides.
A: The Stanley may have been out of stock at the manufacture. As far reaching as the Pandemic has been and is being on both retailers, suppliers, manufactures, and sub contractors and their suppliers, it is of little surprise that anyone in the supply chain could throw a glitch in the process of timely delivery of a product. It looks as if Home Depot or Stanley substituted the "equivalent or better" of the level that they had in stock and available within a reasonable delivery time. Until the Pandemic lets up and people (worldwide) get back to work on near normal schedules this is something I fear we will all have to contend with and get accustomed to.
A: CV, I'm just a HD customer but they sent your question to me, and as a retired engineer I'd say that it's just a misplaced or misprinted decimal place on the 0.15mm/m ie. 0.0059"/39.37" spec. That seems to be a really tight tolerance on a aluminum construction level.
