Starrett 50672 Dial Protractor 6 in Blade Rectangular Head

Product Description

The STARRETT 50672 is a dial protractor designed for precise angular measurement in trade and industrial applications. It features a rectangular head with a dial graduated in 1-degree increments across a 0 to 180 degree range. The 6-inch blade provides a stable reference surface for measuring angles on workpieces, fixtures, and assemblies. At 0.25 pounds, it is lightweight enough for bench use or field work. Licensed tradespeople, machinists, pipefitters, and HVAC installers rely on this type of instrument when accurate angle layout or verification is required during fabrication or installation work.

The 50672 is suited for layout, inspection, and angle-setting tasks in residential and commercial trade work. The rectangular head style seats securely against flat reference surfaces, making it practical for ductwork layout, conduit bending verification, pipe angle checks, and general fabrication measurement. The 1-degree dial graduation gives sufficient resolution for most trade applications where angular accuracy matters without requiring a more complex digital or vernier instrument.

Key Features

• 6-inch blade length for stable contact on workpieces and reference surfaces
• Dial graduated at 1-degree increments for direct-read angular measurement
• Full 0 to 180 degree dial range covers most layout and inspection angles
• Rectangular head design seats flush against flat surfaces for repeatable readings
• Lightweight at 0.25 pounds for easy one-handed use

Compatibility

Designed as a general-purpose dial protractor suitable for trade layout, fabrication inspection, and angular measurement tasks across HVAC, plumbing, electrical, and mechanical applications.

Installation Notes

No installation is required for this instrument. Before taking measurements, ensure the reference surface and blade are clean and free of debris that could affect seating accuracy. Handle the dial face carefully to avoid impact damage that can affect calibration. Periodic calibration checks against a known reference angle are recommended to maintain measurement accuracy in production or inspection environments.
