Woodpeckers Woodworking Rules are straighter, heavier, sit flatter, and are easier to handle and have both a standard and center scale. The inch scale markings are engraved on a 30 degree bevel which reduces parallax for faster, more accurate measuring and marking. Woodpeckers Woodworking Rules have been engineered specifically for woodworking. The beveled edge brings the mark right down to the surface making more accurate markings possible. 36" long. USA made.
