Spi 13-842-0 Steel Rule 6 Inch 5R Rigid

Product Description

The SPI 13-842-0 is a rigid steel rule designed for precise linear measurement in trade and shop environments. Finished in satin chrome plating, it measures 6 inches overall in length and 3/4 inches in width, with a thickness of 0.04 inches. The rule carries 5R graduation markings — 1/100, 1/32, and 1/64 inch increments — making it suitable for layout work, machining setup, and inspection tasks that require multiple reference scales on a single tool. Licensed tradespeople, machinists, and field technicians who need a compact, non-flexible rule for close-tolerance work will find this a standard bench and toolbox addition.

This rule is suited for use in fabrication shops, HVAC unit assembly and measurement, plumbing rough-in layout, and electrical panel work where quick linear reference is needed. The horizontal scale orientation supports straightforward left-to-right reading. The rigid construction means it holds its shape under repeated use without bowing, which matters when scribing or marking cut lines on flat material. No hook is included, and the rule is non-magnetic.

Key Features

• 5R graduation style with three scales: 1/100, 1/32, and 1/64 inch increments
• Rigid construction — no flex — maintains straight-edge accuracy during layout
• Satin chrome-plated finish reduces glare and resists corrosion
• Compact 6-inch overall length fits toolboxes and apron pockets
• Horizontal scale orientation for direct left-to-right reading
• Steel construction for durability in field and shop use

Compatibility

Designed as a general-purpose rigid steel rule suitable for use across trades including HVAC, plumbing, electrical, and light fabrication wherever a 6-inch precision measurement reference is required.

Installation Notes

No installation is required for this measuring tool. Store flat to prevent warping or edge damage. When using for scribing or marking, ensure the rule is held flush against the workpiece surface to maintain measurement accuracy. Handle the satin chrome finish with care to avoid scratching, which can obscure graduation markings over time.
