The Woodworkers Rule is the first tape truly designed for the woodworker. It reads as a standard tape on the front but the patented design on the back allows you to read the footage in any board too. By using the inches on the front and the 4 line rule on the back you can measure any random width board or boards and accurately read the surface measure (S.M.). The Woodworkers Rule is the only tape to be approved by the National Hardwood Lumber Association for determining the surface measure of hardwood lumber. The Woodworkers Rule comes in a durable case and easy to read 1" X 16’ blade with a complete set of instructions. You can check the footage on any board, anywhere, anytime. The Woodworkers Rule is manufactured by a company recognized for it’s high quality. The Woodworkers Rule can be ordered now as a standard tape or soon a standard/metric combination tape.
