Getting things square is a vitally important part of building anything - beit a shed or a car or even a plane.
Out-of-square errors can accumulate during the build and can vastly complicate an otherwise straightforward assembly process.
This excellent square would be an invaluable addition to a builder's tool box. It's made from tough, powder-coated 2mm thick steel.
One side is printed with Metric measurements and the other is in feet and inches. Overall size 24" x 16" (600mm x 400mm)
