Mitutoyo 182-224 Flexible Steel Rule 12 in 3R Graduation

Product Description

The MITUTOYO 182-224 is a flexible stainless steel rule designed for precise linear measurement in trade and industrial applications. At 12 inches in overall length and 1/2 inch wide, this rule features 3R graduation with markings in 1/32, 1/50, and 1/64 inch increments, making it suitable for work requiring multiple fractional references on a single scale. The satin chrome-plated finish reduces glare under shop lighting and resists corrosion from coolants and shop fluids. At 0.0200 inch thickness, the blade flexes to conform to curved or irregular surfaces without losing measurement accuracy.

This rule is used in fabrication shops, machine shops, HVAC duct work layout, plumbing rough-in, and general trade measurement tasks where a rigid rule cannot follow a contoured surface. The 3R graduation style presents three separate scales along the blade, reducing the need to switch tools when working between fractional systems. The horizontal scale orientation suits bench work and layout marking equally well. Tradespeople, machinists, and field technicians reach for this rule when measuring curved pipe, duct flanges, or irregular stock.

Key Features

• Flexible stainless steel blade conforms to curved and irregular surfaces
• 3R graduation provides 1/32, 1/50, and 1/64 inch scales on a single rule
• Satin chrome-plated finish minimizes glare and resists corrosion
• 0.0200 inch blade thickness allows flex without permanent deformation
• 12 inch length covers common layout and measurement tasks in one pass
• No hook, no magnet — straightforward blade-only design for clean readings

Compatibility

Designed as a general-purpose flexible steel rule suitable for trade, industrial, and layout measurement applications where standard rigid rules are impractical on curved or contoured surfaces.

Installation Notes

No installation is required for this measuring tool. Store the rule flat or in a protective sleeve to prevent permanent bending of the blade. Keep the satin chrome surface clean and dry to preserve graduation legibility and corrosion resistance. Do not use as a cutting guide with a utility knife, as blade edge contact will damage the graduation markings.
