Read six scales at once without flipping or fumbling during technical drafting

Triangular scales solve the spatial puzzle of fitting multiple measurement systems onto a single tool without creating confusion. Alvin's 110 Series arranges graduations across three faces, each edge calibrated for specific scaling ratios, architect scales range from 3/32 to 3 inches per foot with one edge graduated to sixteenths, while engineering versions divide inches into 10, 20, 30, 40, 50, and 60 parts. This geometry means you're rotating the scale rather than flipping it repeatedly, keeping your drawing hand stable and your focus on the work.

High-impact plastic construction handles the everyday abuse of studio and fieldwork while maintaining dimensional accuracy. The satin finish resists glare under task lighting, and tapered edges sit flush against paper without creating shadows that obscure your pencil line. Black graduations printed on white provide sharp contrast for quick reading without squinting or second-guessing measurements.

At twelve inches, these scales suit both detail work and broader site plans. Students working through technical drawing courses appreciate the clear markings and durable construction; professionals value having reliable backup scales for job sites where tools take harder knocks than studio equipment typically endures.
