This Stainless Steel 2-in-1 Angle Meter & Ruler with moving blade can calculate internal and external angles and measures length quickly and accurately. A convenient stablelocking function can lock the measurement at any angle or position to transfer angle measurements The ruler's length is up to 600mm(60cm) with scales etched into the faces of the ruler and painted, rather than just surface painted to ensure they don't rub or scratch off easily, ensuring longevity in scale reading. It can rotate a full 360° without restriction and instantly measure angles accurately to within ±0.3° accuracy, so even obtuse angles can be calculated if required, an ideal tool for layout work, table-saw blades, jointer fence, trim installation etc. The flat and straight edges of the ruler are perfect for marking accurate lines with a marker or pencil.
