The only tape approved by the National Hardwood Lumber Association, the Woodworker's Rule helps you determine surface measure (S.M). It reads as a standard tape on the front, but the patented design on the back also allows you to determine the "board feet" of hardwood. By using the inches on the front and the four-line rule on the back, you can measure any random width board or boards and accurately read the surface measure. 16 ft. long with 3/4 in. steel blade.
