Starrett 52674 Steel Rule 12 Inch 4R Rigid Spring Steel

Product Description

The STARRETT 52674 is a rigid steel rule designed for precise linear measurement in trade and shop environments. Made from spring steel with a satin chrome-plated finish, it delivers clear, readable graduations across a 12-inch length and 1-inch width. The 4R graduation style provides four scales on a single rule: 1/16, 1/32, 1/64, and 1/8 inch. At 0.05 inches thick and 0.188 pounds, it is lightweight enough for one-handed use while maintaining the rigidity needed for accurate layout work. A hook is included for end-referenced measuring.

This rule is well suited for HVAC fabrication, plumbing layout, electrical panel work, and general mechanical trade applications. It performs reliably on bench work and in the field. The satin chrome finish reduces glare under shop lighting, making it easier to read graduation marks quickly. The horizontal scale orientation allows straightforward linear reference without repositioning the rule.

Installation Notes

No installation is required for this measuring tool. Keep the rule clean and dry to preserve the satin chrome finish and graduation legibility. Avoid using the rule as a cutting guide with sharp blades, as this can damage the graduated edge and reduce accuracy over time.
