Please select all options.
The limited edition RSA180 Fixed is a precision rafter square with built in spirit level. We set out to create the best metric speed square in the UK! With enhanced features, we've designed this version of the classic RSA180 Fixed to be top of its class when it comes to design, build quality, usability and style.
British-engineered and CNC milled from the highest quality T6 aluminium plate for durability and absolute precision.
It's smart and built to last with a range of features to ensure longevity when used day in day out onsite. To preserve and protect the precision of the angle marks we CNC engraved these at the same time as profiling the tool body. This guarantees the angle marks are true and 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 blue anodised surface making outside reading easy.
The protective anodised seal also helps prevent corrosion and extend tool life.
The fence has a handy spirit level calibrated to the top and bottom visible from all four sides. Really handy for checking the roof pitch or stairs for example.
There are curved scribe notches throughout the length of the tool that relate to many common timber sizes. These can be used with a variety of marking tools such as carpenters pencils, automatic construction pencils or just a standard pencil. These also include thirds for marking rafter cuts.
The scales include:
- Degree scale on hypotenuse edge
- Rafter length per metre of run
- 175mm rule
- Hip/valley rafter scale
- Common rafter scale
- Scribe notches and thirds
