Spi 13-867-7 Flexible Steel Rule 12in 5R Graduation

Product Description

The SPI 13-867-7 is a flexible steel rule measuring 12 inches in overall length and 1/2 inch in overall width. Built from steel with a satin chrome-plated finish, it provides clear, durable graduation marks for precise layout and measurement work. The 5R graduation style includes three scales: 1/100, 1/32, and 1/64 inch, giving the user a range of precision increments on a single rule. At 0.0200 inch thick, the blade flexes enough to conform to curved or contoured surfaces while maintaining accurate readings. This rule is a standard hand tool for machinists, pipefitters, sheet metal workers, and other trades that require reliable shop-floor measurement.

The SPI 13-867-7 suits general measurement and layout tasks in machining, fabrication, HVAC ductwork, plumbing rough-in, and similar trade applications. Its flexible blade makes it practical for measuring inside curved surfaces, tubing, or irregular stock where a rigid rule would lift off the surface. The horizontal scale orientation and satin chrome finish reduce glare and keep graduation lines readable in typical shop or field lighting conditions. No hook or magnetic attachment is included.

Installation Notes

No installation is required for this hand tool. Store the rule flat or in a protective sleeve to prevent bending beyond the intended flex range and to protect the graduation markings from wear. Clean the blade with a dry or lightly oiled cloth to maintain the satin chrome finish and keep graduation lines legible.
