AlumiDrafter

The AlumiDrafter is a mulit-use tool that enables you to measure and draft straight lines, as well as angles and circles. Minimize the need for extraneous protractors and stencils. Easily measure standard angles, draw scaled circles and smooth arcs.

The AlumiDrafter is a single flat tool that stores easily in a notebook or briefcase and is more versatile than a triangular scale.
