Alumicolor Drafting Fan 6in

The Alumicolor Drafting Fan is a handy tool with lots of information on a small, compact space. Made of aluminum with calibrations added using a photo anodizing process, the information will not rub or wear off. There are 8 blades with data on both sides, including: a Center Finding Scale, Imperial Rule, and every standard Architiect, Engineer and Metric Scale used in the industry. The fan is held together by a rivet and small enough to fit in a pocket.
