Precision Drafting, Redefined — The Isomars Adjustable Set Square, 10
Whether you're finalizing a technical blueprint, sketching an architectural elevation, or working through engineering coursework, the Isomars Adjustable Set Square gives you the accuracy and control your work demands. Crafted from high-quality transparent acrylic, this drafting triangle lets you see your lines and reference marks clearly as you draw, so every angle lands exactly where it should.
Unlike fixed set squares, this tool's adjustable angle mechanism lets you dial in and measure custom angles on the fly — one tool doing the job of several. At a comfortable 10-inch size, it's large enough for real drafting work yet compact enough to slide into a drawing kit, bag, or drawer.
A protective cloth cover is included, so your set square stays scratch-free and accurate for years, not just months.
Who it's for: architects, engineers, product designers, drafting professionals, and students who need a reliable, budget-friendly tool that doesn't compromise on precision.
