Aluminium Triangle Rule

The Faithfull Aluminium Triangular Scale Rule is a precision measuring and drawing instrument designed for architects, engineers, and technical drawing professionals. Featuring six different graduated scales (1:20, 1:25, 1:50, 1:75, 1:100, and 1:125), this 300mm rule provides accurate scale measurements for a wide range of technical drawings and plans. The clear, easy-to-read graduations ensure precise measurements across all six scales, making it ideal for producing scaled drawings, interpreting architectural plans, and technical design work. The aluminium construction offers durability whilst remaining lightweight for comfortable handling during extended use. The unique triangular profile provides a practical safety advantage when the rule is used as a cutting guide. This design keeps fingers well away from any knife edge during cutting or scoring operations on card, paper, or other materials, reducing the risk of accidental injury whilst maintaining accuracy.
