The Kincrome Rafter Square (Metric) helps you mark and measure materials quickly and precisely. Its metric markings allow you to use the straight edge as a mm/cm ruler and for marking perfectly straight 90° lines. The 45° edge is great for 45° markings and can be used to determine angles when pivoting. The laser-etched markings are easy to read and the squares are made of anodised aluminium, the extra wide heel provides a firm hold on any material. " />
