The RSA Fixed LE Rafter Square features both the RSA180 LE and the RSA300 LE. A set of unashamedly over-engineered precision squares with an integrated spirit level. With enhanced features, we've designed these versions of our classic Fixed Rafter Squares to be top-class when it comes to design, build quality, usability and style. 

Made in Britain and CNC milled from the highest quality T6 aluminium plate for durability and absolute precision. Developed for quick and simple marking/laying out of roof trusses and other carpentry tasks, made simpler and quicker thanks to a handy spirit-level vial in the fence.

Both squares are smart and built to last with a range of features to ensure longevity when used day in and 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 from 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.

  • CNC machined aluminium

*Our tools are all small batch made and the anodising dye a natural product. As such, slight differences in the shade of blue can occur between batches.
