A compact precision layout tool for accurate marking on site.

It's constructed from 3mm thick anodized aluminum, so that it will resist corrosion and withstands daily site use. It features laser-etched dual metric and imperial scales for clear, permanent markings for any lighting condition. The square itself is compact, the folding design allowing easy transport between tasks.

It provides fixed 45-degree and 90-degree positions to allow consistent squareness checks, and angle layout work.
