General 17 Protractor Rectangular Head 6 Inch Blade

Product Description

The GENERAL 17 is a blade-style protractor designed for precise angle measurement in trade and layout applications. Featuring a 6-inch blade and a 0 to 180 degree dial range with 1-degree graduations, it delivers angle readings accurate to 1 degree (1 minute). The rectangular head provides a stable reference surface against workpieces, structural members, or mechanical components. This tool is well suited for HVAC duct fabrication, pipefitting layout, electrical conduit bending reference, and general sheet metal work where consistent angle verification is required. It weighs 0.186 pounds, making it easy to carry on the job.

This protractor is used across residential and commercial trade work wherever angle measurement and transfer are part of the workflow. Common applications include verifying miter cuts, checking pitch angles on duct transitions, laying out conduit bends, and confirming fitting angles during pipe installation. The 6-inch blade length provides enough reach to span typical workpiece edges without obstruction, and the 0 to 180 degree range covers the full range of standard angle measurements encountered in field and shop environments.

Compatibility

Designed as a general-purpose protractor suitable for use in HVAC, plumbing, electrical, and sheet metal trade applications requiring angle measurement up to 180 degrees.

Installation Notes

No power source or lockout procedure is required for this hand tool. Keep the blade and pivot clean and free of debris to maintain reading accuracy. Do not use the tool as a pry or striking instrument, as this can damage the dial mechanism and affect calibration.
