The Coopay Drafting Triangle is the go-to technical drawing tool for architects, engineers, designers, students, and tradespeople who demand accuracy. Whether you're working on a complex architectural blueprint, a precise engineering schematic, or a geometry assignment, this clear acrylic triangle delivers consistent, clean results every time
Why Choose the Coopay Drafting Triangle?
Inking Edge Technology – The raised beveled edge lifts the ruler slightly off the paper, preventing ink from seeping underneath. This means crisp, smudge-free lines with technical pens, rapidographs, and fine-liners.
Crystal-Clear Acrylic – Unlike cheaper rulers made from frosted or tinted plastic, our clear acrylic lets you see the page underneath. Line up drawings, measure angles, and check alignments without guesswork.
30°/60° & 45°/90° Precision Angles – Designed specifically for isometric drafting, oblique projections, and technical illustrations. The precision-cut angles stay true over years of use
