This 5 ft. rule is made of anodized aluminum. It is 1 1/8" wide and is tempered to stay straight. One side shows graduations in inches along both edges with measurements also from the center of the rule. 

When turned over, the opposite side of the rule has graduations in millimeters and centimeters along one side. Overall ruler length is 60 inches.

Makes a great straight edge and  a perfect guide for marking out 1 1/2 " bias welt strips!
