Cheap Lee Valley Precision Double Square

This square is not a standard production model but one made to our design.

Available with a 4″ blade or a 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.
