Over 100 years ago, the first carpenter's rule that exceeded 4 feet was unveiled. Since then, the workman's measuring tools have come a long way; leading up to the industry's best tape measures, which of course come from DeWalt. The large numbers are easily legible. Many have coated blades that grab material from all four sides. That, in combination with the lock allows you to take readings at your leisure without fear of the tape snapping back and injuring you. These tape measures come in different lengths to fit whatever line of work you are in. Like all DeWalt products, these tape measures are Guaranteed Tough.
