Fowler 54-422-500-0 Digital Protractor 360 Degree

Product Description

The FOWLER 54-422-500-0 is a digital protractor designed for precise angle measurement across a full 360-degree range. Built for trade professionals and precision measurement applications, it delivers a resolution of 0.05 degrees and an accuracy of 0.20 degrees, making it suitable for layout, fabrication, installation, and inspection work. The unit features a magnetic base for hands-free positioning on ferrous surfaces and is powered by a USB rechargeable 9V battery with a built-in status light so users can monitor charge level during use.

This protractor is suited for use in HVAC duct fabrication, pipefitting layout, electrical conduit bending, and general sheet metal or mechanical work where precise angle readings are required. Its compact 2.12 inch by 2.12 inch footprint allows use in tight workspaces on jobsites or in fabrication shops. The magnetic base makes it particularly useful when working on steel panels, ductwork, or pipe where a secure, freestanding position is needed.
