Color: Black/Red

Built to Graft As Hard As You Do.

The TrigJig G-Rafter™ 180 PRO is not just another speed square. It is a robust, precision-engineered roofing tool designed to solve the biggest problem pros face: worn-out markings.

Unlike standard squares where measurements fade over time, the G-Rafter PRO features fully CNC deep-engraved scales. This manufacturing process takes longer, but it ensures your hip/valley and protractor markings will never rub off, no matter how tough the job site conditions are.

Why Upgrade to the G-Rafter PRO?

  • Permanent Precision: The deep engraved (recessed) rulers and scales provide "Enhanced Anti-Wear," dramatically extending the life of the tool.
  • Built-in Spirit Level: Features a high-visibility 360° bubble vial in the fence, allowing you to check level and plumb without switching tools.
  • British Engineering: CNC milled from a solid plate of high-quality 4mm thick T6 Aluminium.
  • Unmatched Accuracy: Machined to tight tolerances with a right-angle precision of +/- 0.008° along the entire length.

Key Features for Framers & Roofers

  • Metric Layout: 183mm rule plus two mini rulers along the fence edge.
  • Smart Scribing: Scribe notches every 5mm for quick marking.
  • Timber Friendly: Includes 1/3rd scribe marks specifically for common timber widths.
  • Roofing Ready: Features a rafter length per metre of run table and a handy birdsmouth line.
  • Dual-Sided Fence: 188mm double-sided fence rule for measuring in any position.
