Keson 6 ft Wooden Folding Ruler – Tenths & Inches (WR1810)
The Keson WR1810 is a wooden folding engineer ruler built for field measurements that use feet and tenths. Instead of converting fractions on the fly, the engineer’s scale is laid out in tenths and hundredths with visible decimal points to help prevent reading errors—ideal for layout, estimating, grading checks, and jobsite documentation.
This folding ruler also includes standard outside markings in feet and inches, graduated to 1/16 in, so it works for everyday carpentry and general construction measuring too. The engineer’s side features red foot marks and clear decimal indicators, making it easier to read quickly when you’re moving between plans, site notes, and real-world dimensions.
