suitable for many roofing and general woodworking projects. Made from heavy-duty steel with a powder-coated black finish for corrosion protection. Clearly graduated in metric and imperial with conversion charts printed on the reverse. Ideal when hand cutting a roof. Hips, valleys, bird beaks, plumb cuts and overhang cuts can all be determined using this square. Rises and pitches can also be calculated using the unique conversion chart on the square itself.
