Apex 623FTN One-piece Steel Rule 3 Ft Sae

Product Description

The APEX 623FTN is a one-piece steel rule designed for precise linear measurement in trade and industrial applications. The blade spans 36 inches with a width of 1.25 inches and a thickness of 0.0625 inches, providing a rigid and stable measuring surface. Graduations are laser etched in both 1/8-inch and 1/16-inch increments across a full SAE scale from 0 to 36 inches. The laser-etched markings resist wear and remain legible under shop conditions. The silver steel finish keeps the rule visible against most work surfaces. This tool is suited for layout, fabrication, and inspection work across HVAC, plumbing, and general mechanical trades.

The 623FTN is appropriate for any trade application requiring a reliable, rigid straightedge with SAE inch graduations. Its 3-foot length makes it practical for ductwork layout, pipe fitting measurements, and electrical conduit routing where longer measurement spans are common. The single-piece steel construction eliminates flex points, making it suitable for both bench work and field use. Tradespeople who need a durable, no-frills measurement reference will find this rule fits standard toolbox storage without modification.
