Engineered for Drafting Excellence

Whether you are mapping landscapes or detailing civil engineering projects, the high-impact polystyrene construction provides a non-warping, stable edge. You can transition between different scales instantly using the intuitive color-coded grooves, eliminating guesswork and keeping your creative focus where it belongs.

Precision GraduationsFull divided increments (10, 20, 30, 40, 50, and 60 parts per inch) for detailed decimal-based scaling.
Color-Coded WorkflowDistinctively colored grooves on each side allow for rapid scale identification in fast-paced environments.
Permanent LegibilityMarkings are die-engraved and printed with rub-resistant black ink for long-term professional use.
Durable ConstructionSolid white polystyrene material resists warping and maintain its edge over years of daily handling.

Why Precision Matters

This STAEDTLER professional series tool provides the rigidity you need for steady lines and the sharply defined divisions required for flawless scaling. Its lightweight 1.6 oz profile makes it easy to handle without sacrificing the professional feel required for serious design work.
