Product Description
This protractor 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 centre. This is especially useful for someone in the field who can only carry a minimum of equipment. To use the protractor, the fulcrum point is pressed into the drawing at the required centre. 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.
