3 Center Rules are great for layout when working from center lines and for laying out detailed joinery. The Chappell Universal Center Rules are made from .029” stainless steel and are flexible enough to work on round logs and uneven surfaces. The front sides have decimal inch rulings as in all Chappell Universal products, with the rulings top and bottom starting from opposite zero points, allowing them to be worked from either side without flipping them over and reading upside down. Model CR118 has a Fraction to Decimal Conversion Chart and Trigonometric Ratio Equations etched on the front side. The backside is a center rule with edge rulings to allow both center work and zero point work on the same rule.
