Unrivalled British Engineering & Precision:

Experience a new level of accuracy that sets your work apart. The Grafter 180 is CNC milled from a single, solid piece of high-quality T6 4mm thick aluminium plate, delivering a right-angle precision of +/- 0.008° along its entire length. This level of workmanship is simply next level compared to laser-cut or cast squares.

• More Than a Square: Integrated Layout Tools:

  • Built-in 360° Bubble Vial: A handy spirit level is integrated directly into the CNC-machined, two-part silver anodised aluminium fence. Visible from all four sides and highly sensitive, it's perfect for marking and finding level marks when roofing and timber framing.
  • Comprehensive Scales & Tables: Features a 182mm main rule, a protractor gauge along the hypotenuse, a double-sided 180mm fence rule, and a crucial rafter length per metre of run table for roofing calculations.

• Smarter, Faster Marking:

  • Stepped Stud-Off Notches: Go beyond simple lines. These unique notches allow for ultra-precise markings that account for the thickness of your marking medium (pencil, scribe, etc.).
  • Versatile Scribing Options: Includes scribe notches every 5mm for parallel lines, 1/3rd scribe marks for common timber widths, and a handy birds mouth line for rafter cuts.

• Superior Build Quality & Lifetime Guarantee:

  • Designed for tradespeople looking for exceptional quality, the Grafter 180 features a robust aluminium construction, stainless steel machine head bolts, and an anodised protective finish.
  • The bright white, laser-etched rulers and markings offer high contrast and extreme abrasion resistance.
