P&N Rafter Square Aluminium 7in Imperial

The P&N rafter square is a 7 inch aluminium square with an imperial scale, built for roofing, framing and general construction layout. It is made from durable aluminium with a corrosion resistant coating, so it is light to carry and stays accurate in site conditions. The laser-etched imperial markings are high contrast and stay readable, and the solid body doubles as a protractor, tri-square, line scriber and saw guide.

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 imperial version?

The imperial scale suits work on imperial dimensioned timber and building materials, where measurements are in inches. If you work in metric, the P&N 180mm metric rafter square is the matching tool.

How does it act as a saw guide?

The thick edge of the rafter square gives you a straight edge to run a saw against for 45 and 90 degree cuts. You mark the line with the square, then hold it in place as a guide while you cut, which gives a clean, straight result.

Is the aluminium body durable?

Yes. The premium grade aluminium is light but strong, and the corrosion resistant coating protects it on site. Aluminium also resists warping, so the square keeps its accuracy where a softer tool would bend or twist.

What is the tri-square function?

The tri-square function means the square can act as a standard try square, a mitre square for 45 degrees, and a depth and height gauge in the one tool. That is part of what makes the rafter square a multi function layout tool rather than a single job square.
