Product Information
Full details
The BlueSpot 180mm Metric Rafter Square is a versatile, all-in-one layout tool designed for carpenters, roofers, and DIY enthusiasts who require precision in their framing and cutting tasks. Its key benefit is its multi-functionality, serving as a protractor, try square, and saw guide, which streamlines the workflow for complex angle measurements. The primary caveat is its 180mm size, which may be insufficient for large-scale timber framing projects that demand a larger 300mm square.

FAQs
Is this tool suitable for Imperial measurements?
No, this specific model is designed for Metric measurements.
What is the primary material used?
The square is constructed from high-quality, reinforced aluminium.
Can I use this as a guide for my circular saw?
Yes, the sturdy, thick edge is designed to act as a fence for straight-line circular saw cuts.
Does it include instructions on how to use the rafter table?
The square features a conversion table etched directly onto the face for quick reference during layout.
How do I ensure the square stays accurate?
Avoid dropping the tool on concrete or steel, as impacts can compromise the precision of the 90-degree angle.
Troubleshooting
Measurements seem off
Check the edges for burrs or debris. If the edge is dented from a fall, it may no longer be perfectly square.
Surface finish fading
Clean the surface with a non-abrasive cleaner and dry thoroughly to maintain the integrity of the powder coating.

Setup, Compatibility & Care
This square requires no complex setup; it is ready for use immediately out of the box. To maintain accuracy, ensure the square is kept free of debris and is not dropped on hard surfaces, as impact can occasionally affect the precision of the edges.
For cleaning, wipe the square down with a dry cloth after use to remove sawdust and moisture. If the tool is exposed to harsh elements or chemicals, a light wipe with a silicone-based lubricant can help maintain the powder-coated finish and prevent potential surface oxidation. Store the tool in a dry, cool place or inside a tool bag to prevent bending or surface damage.
