Readability Features: Starrett satin chrome blades and protractor heads for easier reading are available (on 12" sizes). Direct reading 0 - 180 degrees in opposite directions, permitting the direct reading of angles and supplementary angles. Ease - of - Handling Features: Reversible lock bolt allows choice of which graduated side of the blade faces the operator. The No. 12 is non - reversible, meaning the blade is on the outside of the frame, so the frame stays on the same side of the workpiece. The No. 490 and No. 491 are reversible, meaning there is a shoulder on both sides of the blade, allowing the tool to be reversed so the same angle can be scribed or measured left and right. Long - Life and Accuracy Features: Protractor heads are made of stable cast iron and finished with a choice of attractive black wrinkle finish or smooth black finish. Tempered steel blades with accurate, machine-divided graduations. A spirit level indicates when the base reference surface is level.
