When you’re investing in a rafter square, precision is non-negotiable—but durability is what determines whether your tool will stand the test of time. That’s why we created two levels of professional-grade rafter squares at TrigJig:
Both are CNC-machined for exceptional accuracy, but the PRO takes durability to the next level with advanced anti-wear engineering.
What They Share: Premium Precision as Standard
Both the G-Rafter 7 and the G-Rafter 7 PRO are:
-
Fully CNC-machined from high-quality T6 6082 aluminum
-
Packed with features, including scribe notches every 8th inch, rafter 3rd scribes, rafter conversion tables, and precision stud offs
-
Precision laser-etched 7-inch rule and mini side rule
-
360-degree built-in level for fast, reliable layout work as well as a double sided heel rule
-
Finished with a tough anodised coating and backed by a lifetime guarantee
- One-piece heel for improved durability - even when dropped at height!
In other words, even the standard G-Rafter 7 is a premium precision rafter square, already competing with the best professional squares available today.
The Key Difference: Enhanced Anti-Wear on the PRO
Where the G-Rafter 7 PRO stands apart is in its extra protection against wear.
-
Recessed rulers: Instead of sitting flush on the surface, the rulers are lasered into a CNC-machined recess. Cut deeper into the aluminum. This protects the markings from abrasion, even after years of site use. As shown here on the unlasered tool body below. Most other premium squares on the market are the same as our standard G-Rafter with the marks being lasered onto the flush surface.
-
Deep-engraved protractor angles: The PRO’s scales are CNC deep engraved into the material, making them resistant to fading, chipping, or rubbing away.
-
Long-term precision: These anti-wear upgrades mean the PRO is not just accurate on day one—it’s built to stay accurate after thousands of cuts, measurements, and layouts.
Yes, this takes more CNC machining time. But the result is the most durable rafter square in its class—engineered for professionals who demand tools that last.
Which One Should You Choose?
-
Choose the G-Rafter 7 if you want a precision rafter square that matches the top premium models on the market. It’s robust, accurate, and excellent value.

If you’re looking for the anti-wear rafter square that lasts the longest, the G-Rafter 7 PRO is the clear choice.
