Weems & Plath Protractor Triangle with Handle

Weems & Plath’s Protractor Triangle with Handle is a practical tool for plotting and chart work. Often used in pairs, these triangles provide a simple yet effective method for transferring directional lines without slippage.

Each triangle is inscribed with high-contrast markings in black and red for clarity, while the sturdy handle doubles as a pencil holder for added convenience. The built-in protractor scale makes it easy to draw bearing lines, and the 90° angle is useful for determining lines of position. When used together, one triangle acts as an extension, allowing for seamless plotting across the chart.
