Why the Mars 964 Matters for Your Projects
Whether you are designing structural schematics or teaching advanced geometry, you need a tool that stays true. The heavy-duty blue acrylic construction ensures a flat, reliable edge that resists breakage, while the aluminum thumb screw locks your specific angle in place for repetitive, error-free design work.
The integrated protractor features an inner arc for degree measurement and an outer arc for architectural rise/run slope calculations.
Beveled edges are specifically engineered for use with technical pens and markers, preventing messy ink bleed and smears on your final design.
The transparent blue tint provides high contrast against white paper, making it easier to see your work underneath during long professional drafting sessions.
The aluminum thumb screw provides a firm grip, ensuring your set angle won't slip mid-stroke, maintaining consistency across every page.
