STAEDTLER Triangular Scales 12"

STAEDTLER triangular scales combine versatility with precision engineering, making them essential tools for technical professionals across architecture, engineering, and design disciplines. The 12-inch format delivers optimal balance between portability and usability, fitting seamlessly into drafting kits, field bags, and workspace drawers. Each instrument features three sides with six different scales, maximizing functionality while minimizing bulk. Constructed from durable white solid plastic, the scales resist warping and degradation under standard working conditions. Die-engraved graduations provide permanent, fade-resistant markings that maintain clarity through years of intensive use. The integration of regular and color-coded grooves accelerates scale selection during complex drawing sessions, reducing cognitive load and minimizing transcription errors. Five specialized configurations address distinct professional applications.
