Spi 13-932-9 Steel Rule 6 Inch 4R Satin Chrome

Product Description

The SPI 13-932-9 is a 6-inch tool steel rule finished in a satin chrome-plated coating. It is designed for precise linear measurement in workshop, fabrication, and field service environments. The 4R graduation style provides four graduation scales on a single blade: 1/16, 1/32, 1/64, and 1/8 inch. At 3/4 inch wide and 0.0400 inch thick, the rule is rigid enough for consistent edge referencing without flex. Machinists, pipefitters, HVAC fabricators, and sheet metal workers use this type of rule for layout work, part inspection, and quick dimensional checks. The satin chrome finish reduces glare under shop lighting, making graduation lines easier to read at a glance.

This rule is suited for light fabrication shops, mechanical rooms, and field service kits where a compact, accurate measuring tool is needed. The horizontal scale orientation and included hook make it compatible with standard rule holders and depth gauge attachments. At 6 inches overall length, it fits easily in an apron pocket or tool pouch. It is appropriate for any trade that requires direct, repeatable measurement of parts, cutouts, pipe sections, or material stock during installation or fabrication.

Installation Notes

No installation is required for this measuring tool. When used with a rule holder or depth gauge attachment, ensure the hook is fully seated before taking measurements. Keep the blade clean and free of chips or burrs that could affect reading accuracy. Satin chrome finishes can be cleaned with a dry cloth; avoid abrasive cleaners that may damage graduation markings.
