Spi 13-880-0 Flexible Steel Rule 6 Inch 3R Graduation

Product Description

The SPI 13-880-0 is a flexible stainless steel rule designed for precise linear measurement in trade and industrial applications. At 6 inches overall length and 1/2 inch overall width, this compact rule is suited for close-tolerance layout work, inspection tasks, and dimensional verification. The polished finish provides high contrast for easy reading, and the 3R graduation style delivers three scales on a single rule: 1/32, 1/50, and 1/64 inch. At 0.0200 inch thickness, the blade flexes to follow contoured or irregular surfaces without losing measurement accuracy.

This rule is a practical addition to the toolbox of machinists, pipefitters, sheet metal workers, HVAC installers, and maintenance technicians. Its compact 6-inch length makes it easy to use in confined spaces where a full-size rule is impractical. The flexible stainless steel construction handles contact with fluids and chips without corrosion. The horizontal scale orientation supports straightforward left-to-right reading during layout and scribing operations.

Key Features

• Flexible stainless steel blade conforms to curved or irregular surfaces
• Three graduations on one rule: 1/32, 1/50, and 1/64 inch
• 3R graduation style for versatile measurement reference
• Polished finish for high-contrast, easy-to-read markings
• Compact 6-inch length suited for confined-space layout work
• Non-magnetic, no hook — clean, snag-free profile

Compatibility

Designed as a general-purpose flexible steel rule for use in machining, fabrication, HVAC, plumbing, and maintenance trade applications where a short, flexible measuring blade is required.

Installation Notes

No installation is required for this hand measuring tool. Store the rule flat or in a protective sleeve to maintain blade straightness and protect the graduated markings. Avoid using the rule as a prying or cutting guide, as this can deform the thin blade. Clean with a dry cloth after use to maintain the polished finish.
