Alumicolor 12" Architect Select-a-Scale

Alumicolor's Select-a-Scale is 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 from extruded aluminum with calibrations added using Alumicolor's photo anodizing process.
