Engineer Scale Ruler 12 in Triangular Anodized Aluminum Drafting Scale, 3 Sides with 6 Imperial Scales

This 12 in engineer scale ruler has a triangular body made from anodized aluminum with a black finish. Each of its three sides carries scales, giving six imperial scales: 1:10, 1:20, 1:30, 1:40, 1:50 and 1:60. The markings are laser etched into the surface, so they stay bold and legible.

The flat aluminum body lays flat on the drawing surface for placement. Use it for blueprints, drafting, architecture, civil engineering and technical illustration, or for measuring when drawing designs and drafts. The body has a concave edge.
