Electrical / Tape Measures, Squares & Levels / Rafter Squares

A rafter square is one of those tools you'll reach for countless times throughout the day. It makes marking square lines, checking angles, and setting out cuts quick and straightforward, whether you're framing walls, cutting rafters, or working through a fit-out.

Also known as a speed square or carpenters square, it's designed to do more than check a 90-degree angle. It helps you mark 45-degree cuts, set out roof pitches, and guide a circular saw, all with one compact tool that's easy to carry in a pouch or tool belt.

For carpenters, roofers, and many electricians, it's a simple tool that saves time and helps keep every cut consistent.

A Handy Tool for Everyday Layout Work

A rafter square is built for the kind of marking you do every day. It's commonly used to square off timber, mark roof angles, lay out stair stringers, and guide straight cuts with a circular saw. The raised lip hooks neatly over the edge of the material, so you can line it up quickly without measuring from both sides.

On site, it's often used alongside a combination square, rulers,  and carpenter pencils & sharpeners to keep measuring and marking fast, simple, and accurate.

Simple Features That Save Time

The best rafter squares don't need to be complicated. They just need to be accurate and easy to use.

Most trade models are made from lightweight aluminium that stands up to everyday knocks, while composite versions offer a lighter option that's easy to carry around site. Clear angle markings, roof pitch scales, and scribing notches all help speed up repetitive layout work.

Some useful features include:

• Deeply engraved measurement scales

• 90-degree and 45-degree reference edges

• Raised lip for quick positioning

• Roof pitch and angle markings

• Strong aluminium or composite construction

When the markings are easy to read and the square sits firmly against the timber, the whole job becomes that little bit quicker.

Keep It Accurate

A rafter square only works properly if it stays true.

• Check it every now and then against a known square.

• Keep the edges free from dents and heavy knocks.

• Brush away sawdust before marking.

• Store it where the scales won't get scratched.

It only takes a small amount of damage to affect accuracy. A quick check now and then can save a lot of frustration later.
