Mitutoyo 182-221 Flexible Steel Rule 12 in 4R

Product Description

The MITUTOYO 182-221 is a flexible stainless steel rule designed for precise linear measurement in trade and industrial applications. At 12 inches overall length and 0.5 inches wide, this rule features a satin chrome-plated finish and 4R graduation style, providing four scales on a single blade: 1/16 inch, 1/32 inch, 1/64 inch, and 1/8 inch. The flexible construction allows the blade to conform to curved or irregular surfaces where a rigid rule would produce inaccurate readings. At 0.25 pounds, it is lightweight enough for one-handed use during layout and inspection tasks. Machinists, pipefitters, plumbers, and HVAC technicians use this type of rule for quick field measurements and layout work.

The MITUTOYO 182-221 suits residential and commercial trade environments where flexible measurement is required on curved pipe, ductwork, conduit, or irregular substrates. The horizontal scale orientation supports straightforward left-to-right reading. The rule does not include a hook and is non-magnetic, making it appropriate for use near sensitive electronic components or in environments where magnetic tools are restricted. It is sold individually and packaged as a single unit.

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 flexible blade. Avoid using the blade as a prying or scraping tool, as this can distort the graduation markings. Clean with a dry cloth after use in wet or oily environments to maintain the satin chrome finish.
