Starrett 52673 Steel Rule 6 Inch 4R Rigid Satin Chrome

Product Description

The STARRETT 52673 is a rigid steel rule designed for precise linear measurement in trade and industrial applications. Manufactured from spring steel with a satin chrome-plated finish, this rule delivers durable, glare-reduced readability across a 6-inch overall length and 3/4-inch overall width. The 4R graduation style provides four scales in a single rule: 1/16 inch, 1/32 inch, 1/64 inch, and 1/8 inch. Scale orientation is horizontal. The rule ships with a hook included and has a thickness of 0.05 inches. It is non-magnetic.

This rule is well suited for layout, inspection, and measurement tasks performed by machinists, pipefitters, HVAC technicians, electricians, and plumbers. The compact 6-inch length fits easily in a tool pouch and handles close-tolerance work in tight spaces. The rigid construction keeps the rule flat and stable on a workpiece, making it appropriate for bench work, panel layout, and field measurement where accuracy matters.

Installation Notes

No installation is required for this measurement tool. Store the rule away from abrasive surfaces to preserve the chrome finish and graduation legibility. Periodically wipe clean with a dry cloth to prevent corrosion from moisture or flux residue common in trade environments. The hook end should be inspected before use to confirm it seats flush against a workpiece edge for accurate measurements.
