About this product
This 300mm Faithfull Prestige Tri-Scale Architect Rule is designed for converting ratios when producing technical drawings and plans, suiting architects, engineers and technical designers. It is CNC-machined from heavy-duty aluminium and finished in black anodising for enhanced corrosion protection, with laser engraved scales for lasting measurement accuracy.
The rule's triangular profile allows the six colour-coded scales (1:5, 1:10, 1:50, 1:100, 1:200 and 1:500) to be identified quickly, while also keeping fingers clear of knife blades when cutting or scoring materials. It is suited to drawing offices, educational settings and site-based technical work requiring reliable scale conversion.
