Not all rulers and scales are created equally. Our Alumicolor rulers and scales are checked against a NIST Certified Ruler that is accurate to within .005″ per 12″. This makes these  products among the most accurate in the industry and ones you can count on for  architects, engineers, realtors, landscapers, builders, electricians, and other professionals.
