A Square built for both precision and durability. Excellent for construction, workshops and carpentry work. The blade is 45 mm wide to accommodate work with standard stud dimensions and a center line makes it easy to quickly mark out both sides of a stud. The blade also has scribing notches spaced 5 mm apart, these can be used to draw or cut a line parallel along an edge.

A unique assembly technology with strong custom riveting and a 1.5 mm thick high-strength stainless steel blade. That provides an extremely durable design that can withstand tough working environments and will last a long time. A precision cut blade and riveting with minimal tolerances provide extremely high precision; angle tolerance ±0.03° (±0.5 mm/m).
