Our ULTRATEST Steel Rules are made to exacting tolerances in order to meet accuracy standards set forth by the federal government. The ultra-fine graduations are etched in black and set against a satin chrome finish for easy reading. In addition, the markings are resistant to wear for the life of the rule. We offer ULTRATEST rules in lengths of 6, 12, 18 and 24 in., as well as five variations of Metric and English graduations. Includes a plastic carry case.
