The Triangular Scale Ruler T1 measures 300mm for technical drafting and blueprint work. Six metric ratios ranging from 1:10 to 1:500 provide precise calibration for engineering layouts. A rigid, non-foldable body maintains structural integrity during heavy use.
Key Features
- Six Metric Scales: Ratios spanning 1:10 to 1:500 across three drafting sides. Handles standard architectural drawing tasks without manual math.
- Color-Coded Grooves: Inlaid colored stripes distinguish the different scale faces. Speeds up identification during rapid technical drawing sessions.
- 300mm Rigid Body: Non-foldable plastic build resists bending or physical warping. Withstands road dust and humidity in BD work environments.
Frequently Asked Questions
What are the scales on a triangular ruler?
The T1 model provides six metric ratios including 1:10, 1:20, 1:25, 1:50, 1:75, and 1:100. These allow for direct reading of scaled blueprints without calculation.
How to use a triangular scale ruler for drafting?
Match the ratio on the ruler edge to the scale indicated on the drawing. The color-coded fluting helps you find the correct side instantly.
