Alumicolor Calibrated Aluminum Triangle, 30/60/90

Alumicolor Calibrated Triangles are made from durable tempered aluminum, offering a sturdier alternative to plastic triangles. The photo-anodized calibrations are built directly into the finish, so markings won’t fade or rub off with regular use. Smooth surface helps protect your work area and glides easily across paper.

These 30°/60°/90° triangles are available in 6”, 8”, and 10” sizes and include precise calibrations in both inches and centimeters. Finished in classic silver aluminum, they're great for drafting, design work, calligraphy layout, and other precision-focused creative endeavors. Each triangle also features a range of circle templates.
