    This protractor has the same type of head as the No. 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.) β—† When not in use, the fulcrum point can be drawn back into the hub and frictionally held in a safe position β—† Satin chrome finish for ease of reading and resistance to rust β—† Furnished with one needle point and one cone point Learn More
