Keson wood rulers have long been an essential tool for carpenters, mason’s, plumbers and all types of tradespeople. They extend to over 6 feet (2m). They enable you to draw straight lines up to these lengths without the use of a chalk line or mason’s line.
The brass extender makes measuring tight openings a snap. Extends up to 6 inches, and sliding rule stops at each end to resist falling out. A very useful tool for carpenters.
This wood ruler has inside marking. Numeration starts on the inside of the rule, so the measurement lies close to the work.
Designed for engineer or other measurements requiring tenths and feet. Decimal points on engineer’s scale prevent reading errors.
This 2-meter folding ruler measures in mm, cm, and meter graduations.
Designed for use in bricklaying and mason’s work, with a brick mason’s scale on the inside.
