P&N Rafter Square Aluminium 180mm Metric

The P&N rafter square is a 180mm aluminium square with a metric scale, built for tradespeople, roofers and builders who want accurate layout in a compact tool. The aluminium body is light and corrosion resistant, and the anodised finish protects it on site. The laser-etched metric markings stay readable, the integrated protractor scale measures angles, and the thick edge acts as a saw guide for 45 and 90 degree cuts.

Frequently Asked Questions

What is a rafter square used for?

A rafter square is the layout tool for marking angles on rafters, determining roof pitches and laying out hip and valley cuts. Its compact size fits on a rafter, and the scale gives quick angle and pitch references for cutting timber.

Why choose the metric version?

The metric scale suits work on metric dimensioned timber and building materials, which is the standard on Australian sites. If you work in imperial, the P&N 7 inch imperial rafter square is the matching tool.

How does the protractor scale work?

The integrated protractor scale on the square body lets you set and mark angles directly, which is useful for measuring existing roof pitches and transferring angles to a cut. It turns the rafter square into a compact angle tool.

Is the anodised finish important?

The anodised surface resists corrosion and wear, so the square keeps its appearance and its accuracy on site. Aluminium also resists warping, so the tool stays true where a softer material would bend.

Can I use this square for marking out studs?

Yes. The 180mm length is compact enough to work on studs and framing members, and the metric scale plus protractor let you mark out lines and angles quickly. It is a good all round layout square for a carpenter or builder.
