Description

Available with a 4" or 6" blade, it features a slimmer than normal stock and an accuracy guaranteed to be better than 0.001 per inch, exceeding our regular machinist's squares. It doubles as a try square and a precision square, suitable for both layout work and machinery set-up and checking. The precision open-work casting not only provides the accuracy required but avoids the stock-heavy feel of most machinist's squares. The blade locks securely in any position from full left to full right. Made in USA.

Review Summary

Take the best features of a combination square (easy adjustability and measurement markings), mix in the best features of a machinist square (precision and pocket portability), and you’ll see why we like this 4" double square. The blade slides through the body for gauging reveals on cabinet doors or for setting up saw blades and router bits, without being cumbersome like a full-size combo square.

Review Summary

I bought one of these 4" double squares in about '04 or '05. And it worked exactly as advertised for a while. But now here we are several years later (and after having given mine lots of use) and now I find that the ruler body will not stay put when dogged down with the thumb wheel.

…

The bearing surfaces have worn and the ruler does change position pretty easily when I'd prefer that it be locked down tight. Perhaps this is an issue that's been solved since I got mine - or maybe not. All I know is that I'm hunting for a replacement from a different manufacturer now, hoping that my mileage changes. This is my first uneven experience with a Lee Valley tool. I still generally love their stuff, but this double square isn't on that list any more.
