Spi 13-924-6 Flexible Steel Rule 18 Inches

Product Description

The SPI 13-924-6 is a flexible steel rule measuring 18 inches in overall length and 3/4 inches in overall width. It features a black chrome-plated finish over a steel construction, providing durability and contrast for easy reading in low-light or high-glare conditions. The rule carries dual English and metric graduations, with English markings in 1/2, 1/32, and 1/64 inch increments. At 0.0200 inches thick, the blade flexes to conform to curved or irregular surfaces, making it practical for layout, inspection, and measurement tasks that a rigid rule cannot handle. Machinists, fabricators, pipefitters, and HVAC sheet metal technicians commonly use this type of rule as a daily shop and field tool.

This rule is suited for both shop and field applications where precise linear measurement is required on flat or contoured workpieces. The flexible blade allows it to wrap around pipe, ductwork, or formed sheet metal to take accurate measurements. The horizontal scale orientation and black chrome finish reduce eye strain and minimize glare under shop lighting. It ships as a single unit and requires no accessories for immediate use.

Installation Notes

No installation is required for this measuring tool. Store flat or rolled loosely to prevent permanent set in the blade. Avoid exposing the rule to abrasive surfaces that could wear graduation markings. Clean with a dry cloth to maintain the black chrome finish and marking legibility.
