Product Information
Full details
The BlueSpot Tri Square 300mm is a professional-grade precision tool essential for carpenters, joiners, and dedicated DIY enthusiasts who demand consistent accuracy for right-angle checks and marking. Its primary benefit lies in its dual-scale metric and imperial graduations, which allow for rapid switching between measurement systems, though users should note that the metallic construction may require occasional wiping to maintain the effectiveness of the anti-rust lacquer over long periods of heavy outdoor use.

FAQs
Is this tool suitable for outdoor use?
Yes, it features an anti-rust lacquer coating, though you should wipe it dry after exposure to rain or humidity.
Does it measure in both metric and imperial?
Yes, the tool features embossed scales for both 300mm and 12-inch measurements.
Are the markings painted on?
No, the markings are embossed into the material, which ensures they remain legible for the life of the product.
What materials can I use this on?
It is primarily designed for use on wood, but can be used for marking on any soft or semi-hard material.
Does this require any calibration?
The tool comes calibrated from the factory, but should be handled carefully to maintain its squareness.
Troubleshooting
Measurements are becoming difficult to read due to dust
Use a soft, damp cloth to remove debris; the embossed markings are designed to be easily wiped clean.
Square feels slightly inaccurate after a drop
Check the edge against a known true corner; if a burr has formed, use a fine-grit file to carefully remove the metal protrusion.

Setup, Compatibility & Care
This tool requires no formal setup—it is ready for use immediately upon unboxing. To ensure the longevity of the tool, store it in a dry tool box or hang it by the integrated hole when not in use. To maintain the accuracy and the anti-rust coating, avoid dropping the square on concrete or steel surfaces, as burrs on the edges can impact the accuracy of right-angle checks. If the tool comes into contact with moisture, wipe it down with a clean cloth immediately, and occasionally apply a light machine oil to the surface to preserve the protective lacquer.
