Faithfull Prestige Tri Scale Architect Rule 12" / 300mm

The Faithfull Prestige Tri-Scale Architect Rule is a professional-grade precision instrument designed for accurately converting ratios when creating technical drawings and plans. Manufactured from heavy-duty aluminium using CNC machining, this 300mm rule delivers the accuracy and reliability that architects, engineers and technical designers require for scale work. The distinctive triangular profile serves dual purposes – it enables easy identification of the six colour-coded scales whilst keeping your fingers safely away from knife blades when cutting or scoring materials. The black anodised finish provides enhanced corrosion protection for long-term durability, whilst laser engraved scales ensure outstanding measurement accuracy that won't fade or wear over time. This architect rule features six commonly used scales (1:5, 1:10, 1:50, 1:100, 1:200, 1:500) with colour-coded inserts for quick recognition, making it ideal for architectural drawings, site plans, and scale conversions. The precision engineering and robust construction make it suitable for professional drawing offices, educational environments, and site-based technical work where reliable scale conversion is essential. Backed by a 10 year guarantee, this rule is manufactured to the highest standards and represents a professional-grade solution for anyone working with scaled technical drawings.
