Best adjustable metric rafter square with permanent anti-wear markings for repetitive roof truss layouts.
The TrigJig RSA180 Adjustable Rafter Square V2 delivers unprecedented layout speed and uncompromising accuracy for professional framers and roofers. Precision CNC-machined in Great Britain, this V2 model features a highly innovative adjustable fence, allowing tradesmen to "set and forget" angles for rapid, repetitive roof truss marking without the need for separate stair gauges. To guarantee lifetime readability, the protractor angles are CNC deep-engraved directly into the aluminium body, while the 175mm and 100mm rulers are laser-marked inside shallow recessed pockets. This advanced anti-wear engineering ensures the scales never contact the workpiece when laid flat, permanently preventing abrasion and fading.
The Pro's Equation: Eliminating Layout Drift and Setup Time
In professional roofing, repetitive setup times and layout drift are silent profit killers. Standard squares require constant resetting or easily lose their printed markings, leading directly to costly measurement errors and timber waste. The TrigJig RSA180 V2 eliminates these vulnerabilities. By utilizing the adjustable arm for instant seat and plumb cuts, you drastically reduce layout downtime. When combined with multi-functional scribe notches explicitly tailored for common timber widths, this tool ensures every mark is dead-on accurate. Investing in this wear-resistant, British-engineered instrument translates directly to faster workflows, zero guesswork, and maximum ROI on the job site.
Why Pros Choose the TrigJig RSA180 V2:
-
Adjustable Fence System: "Set and forget" mechanism allows for rapid, repeatable plumb and seat cuts.
-
Deep-Engraved Angles: Protractor markings are CNC machined into the metal, ensuring they will never rub off.
-
Recessed Rulers: Laser-marked scales sit inside shallow pockets, protecting them from surface abrasion when laid flat.
-
Smart Scribing Notches: Includes vertical scribes, parallel stud offs, and 1/3rd notches for rapid common timber layout.
-
Anti-Glare Anodized Finish: A 15-micron thick blue anodized coating provides high contrast for easy outside reading and extreme tool longevity.

Does the adjustable fence lose its exact zero-point accuracy over time?
No. The RSA180 V2 is fully CNC machined on a state-of-the-art vertical machining center. This meticulous manufacturing process ensures that when the adjustable fence is returned to its baseline, it snaps back to exactly zero without any mechanical slop or layout drift.
Will the measurements rub off after heavy job site use?
Absolutely not. TrigJig engineered this square specifically for enhanced anti-wear. The protractor angles are physically deep-engraved into the metal, and all ruler gauges are laser-marked inside shallow recessed pockets so they never physically touch the timber when laid flat.
Do I need separate stair gauges to use this square for repetitive cuts?
No. The integrated adjustable fence arm eliminates the need to carry separate stair gauges. You can lock in your desired angle once and instantly replicate complex rafter, seat, or plumb cuts with absolute consistency across multiple timber pieces.
