Overview

The Westcott W-43 6-Inch Metric Protractor Ruler is a dual-purpose measuring tool that combines a straight-edge metric ruler with an integrated protractor for angle measurement. Made from transparent, laminated plastic, it allows you to see the lines and marks underneath while positioning it, which is particularly useful when working with technical drawings, geometry homework, or graph paper. The laminated surface adds a layer of protection against scratches and everyday wear, helping the markings stay legible over time.

At 6 inches in length, the W-43 is compact enough to fit in a pencil case or small supply pouch, making it a practical everyday carry for students, engineers, and designers who need quick angle and distance measurements on the go. While it is not intended for large-scale drafting, its combination of two measurement functions in a single, durable tool makes it a reliable choice for routine precision work at a modest size.
