Wood Rulers

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. Folds up to 9-1/2 inches.


  • Steel springs have a precision lock action for extra strength when extended.
  • Cleanly machined edges allow the rule to be snapped together easily and hold it stiff while measuring.
  • Weather resistant markings have tough, clear protective coating.
