Alumicolor is proud to introduce the Alumicolor Select-a-Scale. An ultra convenient and functional drafting tool that allows architects and engineers to select multiple scales all in one product. The unique design incorporates a sculptured arch on the bottom for ease of movement. A rotating rod on the top displays one of six available scales while the solid aluminum base has fixed scales on the front as well as a raised inking edge. Made of extruded aluminum with calibrations added using Alumicolor's photo anodizing process.
