Steel Protractors C19 Steel Protractor 0-180º This is a highly useful and accurate tool for setting bevels, transferring angles, small squaring tasks, checking cutter clearances within certain limits, and many other applications. • Double graduations from 0-180º in opposite directions permitting the direct reading of angles and supplementary angles • The back of the tool is flat for ease of use • The blade can be locked firmly at any angle by the lock nut • Satin chrome finish for ease of reading and resistance to rust C183 Steel Protractor 0-180º This protractor is exactly the same as the C19, except that is has a rectangular head, thus providing four convenient working edges. C182 Steel Protractor 0-180º This protractor has the same type of head as our 19 but it is designed for draftsmen, civil engineers, and others who need a protractor that will allow the drawing of any number of radial lines at any angle through a common center. This is especially useful for someone in the field who can only carry a minimum of equipment. Weight is approximately 3 ounces. To use the protractor, the fulcrum point is pressed into the drawing at the required center. This is done by removing the fulcrum point from the hub, pressing it in the drawing, and then placing the protractor hub over the fulcrum point. The desired angles can then be laid out. The fulcrum point can be left in the tool. Press the whole tool down so that the point penetrates the drawing. (However, this will make it harder to find the center.)
