Straight Edges is a Cutting Guide tool for copying a straight line from one location to another or checking the straightness of a line already drawn. A straight edge with equally spaced markings on it is called a ruler. Straight Edges are not only a great way to mark, test or transcribe perfectly straight lines, but also efficient in measuring short distances (96 inches or less, or 8 feet). They also feature graduations and length markings for ease of use in the construction process. Shop now at Tiger Supplies!
