Adjustable Hook Rulers - English/Metric Graduations

PEC Tools Adjustable Hook Ruler | Hardened Steel, Made in USA Precision begins at the edge. The PEC Tools Adjustable Hook Ruler is the ultimate solution for taking accurate measurements from the end of a workpiece or reaching into tight recesses where a standard rule falls short. Engineered for professional machinists, woodworkers, and fabricators, this tool eliminates the guesswork of "lining up the zero." Why Choose the PEC Adjustable Hook Rule? Superior Readability: Our high-contrast, hard chrome finish is non-glare, making it easy to read even under bright shop lights. The graduations are precision-etched and black-filled for long-lasting clarity. Built for the Grime: Unlike cheap stamped alternatives, our rules are made from premium Carbon Steel—fully hardened and tempered to resist bowing, nicks, and wear. The Hook Advantage: The adjustable hook allows you to "catch" the edge of your work for a perfect zero every time. It can be reversed for use on either side of the rule or removed entirely for standard use. Industrial Thickness: At .040" thick, this rule offers the perfect balance of rigidity and a slim profile for tight tolerances.
