The RSA300 Adjustable V2 Rafter Square is a large 300mm Rafter Square.

With enhanced features, we've created it to be top of its class when it comes to design, build quality, usability and style.

As the bigger brother to the RSA180 Adjustable, it's ideal if you work with big timber. 

Feature-packed with several marking gauges and parallels, the RSA300 Adjustable can be used in many carpentry and fabrication projects. Though its speciality is for roofing, timber framing and when working with large trusses and timber.

ADJUST, SET, GO >>

The square features a handy adjustable fence so you can 'set and forget' when marking out multiple roof trusses. No separate stair gauges needed! It makes repeat cuts quick and easy.

ENHANCED ANTI-WEAR

To preserve and protect the precision of the protractor angles we CNC engraved these at the same time as profiling the tool body. Plus, as they're deep engraved they won't rub off! The ruler gauges are laser marked inside shallow recessed pockets that prevent them coming into contact with workpieces when laid flat. The white marks are clearly visible on the anti-glare anodised surface making outside reading easy.

FEATURE PACKED

There are several vertical scribes and parallel stud offs throughout the tool that relate to many UK/EU and Australian common timber sizes too. These also include handy thirds for quick marking of rafter cuts. Use the scribe notches on the parallel slots to reveal your pencil mark when laying out to account for your pencil thickness and bring more precision to your work.

It's loaded with handy and versatile features, including:

• 300mm laser-marked rule inside a recessed pocket - this avoids wear when the tool is laid flat
• Anti-wear recessed side rule
• Adjustable arm for quick seat and plumb cuts
• Common rafter scale
• CNC-engraved degree marks for wear resistance
• Multiple vertical and parallel scribes for precision layout
• Thirds scribe notches for marking common timber dimensions
• 15 micron thick anodised finish for durability and tool longevity
• Designed and made in Great Britain

The precision and workmanship from our manufacturing process is unrivalled and next level compared to mass-produced, laser cut or cast rafter squares. The RSA300 Adjustable V2 is built to an extremely high standard, made for tradespeople who are looking for exceptional durability, design and quality from their tools.
