01MEASURING TOOLS & SENSORS
Six scales in one precise instrument
Resting on the drafting table, this triangular ruler is the quiet backbone of technical precision. Its solid aluminum body holds its shape under pressure, offering a stable platform for every line drawn.
Designed for architects, engineers and students, it provides six different metric scales on three sides. It suits those who value accuracy and require a tool that performs reliably across various professional applications.


02MATERIALS
Solid aluminum for structural stability
Crafted from high-grade solid aluminum, the ruler resists the flex and warping common in plastic alternatives. This material choice ensures the edges remain true over time, providing a consistent reference point for your measurements. The black finish complements the metallic rigidity, creating a tool that feels substantial yet refined in the hand.

04DIMENSIONS
Thirty centimetres of practical reach
At 30cm long, the ruler offers sufficient length for most standard drawing tasks while remaining manageable on a desk. Weighing only 80g, it sits lightly on paper without shifting, allowing for smooth, controlled strokes. The compact form factor makes it easy to store in a pencil case or slide into a portfolio alongside other essential instruments.
APPLICATION
Precision for architecture and engineering
Ideal for professionals in architecture, engineering and technical drawing, this tool supports the exactitude required in these fields. Whether you are a student learning the craft or an established draftsman refining a blueprint, the multi-scale design accommodates the full spectrum of project requirements. It bridges the gap between conceptual sketching and final technical rendering.
