ABSTRACT A metric rafter square has a body and tongue with lengths of at least 300 mm and 400 mm respectively and scales along their outer edges in millimeters. A rise per meter table on the body includes a series of entries which cooperates with a rise per meter scale disposed along the tongue and pivot points disposed along the body. The rise per meter scale on the tongue is cooperatively compressed and has gradua- tions and a series of numerical values along its length for the graduations which are greater than the actual values represented by the unit length of the scale designated thereby. The required angles for end cuts are established between the preselected pivot points on the body and coopera- tive points on the rise per meter scale and the metric scale of the tongue. Methods are disclosed for the use of the metric square in the scribing of framing members with the appropriate lines to establish lengths and desired angles for end and side cuts.
