TrigJig RSA180 Adjustable Rafter Square

It makes repeat cuts quick and easy and as this model is fully CNC machined on our incredibly precise, state-of-the-art vertical machining centre, the fence quickly snaps back to exactly zero when required. 

As with all the RSA squares the RSA180 Adjustable has many useful features that include:

• 175mm laser marked rule inside a recessed pocket - this avoids wear when the tool is laid flat
• Adjustable arm for quick seat and plumb cuts
• Common rafter scale
• CNC engraved degree marks for wear resistance
• Pencil scribe notches and thirds for marking common timber dimensions
• 4mm anodised aluminium surface finish for toughness and tool longevity
• Designed and made in Great Britain
