Dual-Geometry Precision: A comprehensive set featuring both a 45/45 and a 30/60 square, providing the essential angles required for architectural drafting and isometric projection.
Integrated Inking Edge: Specifically designed with a specialised offset edge to prevent ink from smearing or capillary action under the square, ensuring clean, crisp lines when using technical pens.
High-Clarity Transparent Orange: Manufactured from a vibrant, transparent material that provides high visibility against white paper while making the tool easy to locate on a busy drawing board.
Permanent Engraved Graduations: Features deeply engraved markings in both metric (cm) and imperial (inches), ensuring measurements remain legible and accurate even after years of frequent use.
Professional Drafting Sizes: The 250mm and 350mm proportions offer a generous reach for large-scale technical drawings, providing a stable guide for long, precise vertical or angled strokes.
