FIS 30cm Triangular Scale Architecture Ruler

Accelerate complex drafting blueprints, engineering site surveys, and landscape design mockups using the standalone FIS 30cm Triangular Scale Architecture Ruler (Model FSRUTR30). Formulated with a classic three-sided prism body, this professional technical drafting instrument hosts multiple precision-calibrated reduction scales simultaneously to simplify scaling tasks without arithmetic steps.

Key Specifications & Features:

• Physical Sizing Profile: Standard 30cm length triangular design featuring 6 distinct integrated scaling faces
• Scale Ratio Configurations: Professionally calibrated scale markings providing 1:20, 1:25, 1:50, 1:75, 1:100, and 1:125 ratio values
• Material Construction: High-impact, dimensionally stable white plastic core that resists thermal expansion or warp distortion over time
• Visual Index Tracking: Multi-color coded grooves running along the prism valleys allow for fast orientation tracking of target ratios
• Primary Use Cases: Architectural construction blueprint mapping, civil engineering surveys, design scaling, and drafting rooms
