602342 A framing square (100) that provides tabulated calculations aligned with indicia that enable construction of equal and complex unequal pitch framing members without the need for complex trigonometric calculations is disclosed. The square is not limited to use with a single base unit of measurement, e.g. inches or millimetres, and provides limited tabulated information for use in calculating lengths, distances, and angles at which to cut framing members. |
