G-Rafter 180 vs G-Rafter 180 PRO: Which Rafter Square Is More Durable?

When choosing a rafter square, accuracy is vital — but a tool’s durability can make just as much difference on site. Whether you’re framing roofs, marking angles, or checking squareness, you need a durable rafter square that stays precise through years of use.

So, which one holds up better over time — the G-Rafter 180 Standard or the G-Rafter 180 PRO?

Precision Engineering in Every Detail

Both versions share the same DNA. Each G-Rafter 180 is a CNC-machined from premium 6082-T6 aluminium, creating a robust, stable construction to ensure accuracy that lasts.

Key features include:

• CNC-machined aluminium square
• Laser-etched metric scales for fast, reliable marking.
• Scribe notches in 5mm increments for repeatable, consistent cuts.
• 1/3rd scribe marks for common timber widths
• Rafter length per metre of run table
• Integrated level vial for quick on-site checks.
• One-piece heel that adds strength and alignment accuracy.
• Tough anodised finish to protect against corrosion and wear.
• Lifetime guarantee for total peace of mind.

Even the Standard G-Rafter 180 outperforms typical rafter squares — but the PRO version takes the idea of a durable rafter square to the next level.

The G-Rafter 180 PRO: Designed for Maximum Durability

The G-Rafter 180 PRO is built for professionals who expect their tools to perform for decades. What sets it apart is its anti-wear design.

Instead of relying on just surface-etched markings like the standard and most other premium metric rafter squares on the market. The G-Rafter 180 PRO features deep-engraved, recessed scales cut directly into the aluminium during CNC machining. These markings sit below the surface, protected from scratches, scuffs, and fading — even after years of hard use.

This design makes the G-Rafter 180 PRO one of the most durable rafter squares available today, maintaining its readability and precision where other tools would wear out.

Which One Should You Choose?

Both the Standard and PRO versions offer professional-grade precision, but they serve slightly different needs:

• Choose the G-Rafter 180 Standard for excellent accuracy, everyday reliability, and great value. 

• Choose the G-Rafter 180 PRO if you want the ultimate durable rafter square — one that will stay sharp, clear, and dependable for a lifetime of work.

Built to Go the Distance

Every TrigJig tool is designed to outperform expectations, but the G-Rafter 180 PRO sets a new benchmark for long-term reliability.

If you’re searching for a durable rafter square that combines precision engineering with lasting protection, look no further — the PRO is built to go the distance.
