Mitutoyo 182-241 Steel Rule 18 Inch 4R Rigid

Product Description

The MITUTOYO 182-241 is a rigid stainless steel rule designed for precise linear measurement in trade and industrial environments. The rule measures 18 inches in overall length and 1-3/16 inches in overall width, with a thickness of 0.05 inches. It carries a 4R graduation pattern, providing four scales on a single rule: 1/16, 1/32, 1/64, and 1/8 inch increments. A satin chrome-plated finish reduces glare under shop lighting and protects the surface from corrosion. Machinists, pipefitters, HVAC technicians, and fabricators use this rule for layout work, scribing, and quick reference measurements on the bench or in the field.

This rule is suited for residential and commercial trade applications where a durable, easy-to-read measuring reference is needed. Typical use cases include ductwork layout, pipe fitting measurement, sheet metal fabrication, and general mechanical assembly. The horizontal scale orientation makes it straightforward to align against workpieces. No hook or magnetic base is included, keeping the profile flat and easy to store in a tool pouch or service bag.

Key Features

Compatibility

Designed as a general-purpose rigid steel rule suitable for trade and industrial measurement tasks across HVAC, plumbing, electrical, and mechanical fabrication work.

Installation Notes

No installation is required for this hand tool. Store the rule flat or in a protective sleeve to prevent edge damage and maintain graduation legibility. Avoid using the rule as a pry or scraping tool, as this can deform the edges and compromise measurement accuracy. Clean with a dry cloth after use to preserve the satin chrome finish.
