General 678MED-I Steel Rule 6 in 4R English Metric

Product Description

The GENERAL 678MED-I is a rigid stainless steel rule designed for precise linear measurement in trade and light industrial applications. Measuring 6 inches in overall length and 3/4 inches in overall width, it features a polished silver finish and a 4R graduation style that includes four scales: 1/16, 1/32, and 1/64 inch on the English side, and metric graduations as well. The horizontal scale orientation makes readings straightforward in bench or field use. This rule is a standard hand-measurement tool carried by HVAC technicians, plumbers, electricians, and pipefitters for layout, inspection, and general dimensioning work.

The 678MED-I suits residential and commercial service environments wherever quick, accurate linear measurement is needed. Its compact 6-inch length fits easily in a tool pouch or kit bag, making it practical for confined-space work such as panel layout, pipe fitting, ductwork sizing, and equipment clearance checks. The stainless steel construction holds up to shop fluids and repeated handling without significant wear to the graduation markings. No hook is included, and the rule is non-magnetic, so it will not attract ferrous debris on a workbench.

Key Features

• Rigid stainless steel construction resists flex and corrosion during regular trade use
• 4R graduation style provides four measurement scales on a single rule: 1/16, 1/32, 1/64, and 1/8 inch
• Dual English and metric graduation for versatile measurement reference
• Polished silver finish enhances graduation visibility in varied lighting
• Compact 6-inch length and 3/4-inch width fit standard tool pouches
• Non-magnetic design prevents ferrous particle attraction in shop environments

Compatibility

Designed as a general-purpose precision steel rule suitable for use across HVAC, plumbing, electrical, and mechanical trade applications requiring short-range linear measurement.

Installation Notes

No power source or system shutdown is required for use of a steel rule. Store the rule away from abrasive surfaces to preserve the polished finish and graduation legibility. When using for layout or inspection on live equipment, follow applicable lockout/tagout procedures before placing hands near energized components. Handle edges with care, as the stainless steel ends may be sharp.
