Alumicolor scales are extruded from quality aluminum. All calibrations are photo-anodized and will not clean off. All edges are ultra-smooth and will always give an uninterrupted line free from “ticks” common to engraved or printed lines. Alumicolor’s solid drafting scales are the ultimate for accurate, professional use. Satin-smooth anodized aluminum scales are a pleasure to use.
Scales 10, 20, 30, 40, 50, 60 parts per inch
