G-Rafter 180 vs 180 PRO: The Most Durable Rafter Squares
October 20, 2025
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.

Which is the best Angle Finder?
April 10, 2025
We're proud to offer the largest range of precision Manual Angle Finders on the market. Without the need for batteries, our robust and ultra precise proctractors won't let you down and are built to last a long time. Backed by our lifetime warranty against manufacturing defects.
With such a wide range of Angle Finders to choose from, we sometimes get asked which is the best size of Angle Finder to go for? It really depends on your preference and the types of projects you will be working on. Here are some of the different features.
-
The AF6 is our best seller and measures 6 inches from the centre bolt. It shows the single, protractor and mitre readings on the display. The stubby-armed version of this has 1 shorter arm, which is handy for measuring in hard-to-reach spots.
-
We have the AF4 pocket-sized version, which does exactly the same as the AF6 but is smaller and lighter at just 130g. This is very handy if you are say on the job site, carrying multiple tools and want to have lighter more compact options.
-
Both the AF4 and the latest model of the AF6 have a recessed bolt at the pivot point which allows the tool to sit flat against the work surface.
-
The longer AF9 and AF16 versions are really useful for when you want to take a measurement across a longer span. For example, on uneven surfaces like in older houses or for built-up/low corners on drywall/plastering work. The AF9 and AF16 both feature a rise-and-run reference table.
-
The AF16 includes a quick-reference table for coving angles. The table clearly displays the mitre and bevel settings for your mitre saw based on the most common corner angles and coving spring angles (45° & 38°) to cut 'on the flat'.
-
All of our angle finders are fully CNC machined from 1/4 inch thick high-quality T6 aluminium, are treated to a protective anodised layer and then laser marked. The AF9s and AF16s are also hand-finished with red-painted locating arrows.
-
All of the angle finders also feature a secondary dial for more acute angles which can be used in conjunction with your mitre saw and a pre-cut, 45-degree block.
Some popular combinations are to have a smaller and longer version, such as the AF6 and AF16 or AF4 and AF9 for example. Or to have an AF6 or AF9 set with the stubby-armed version.
