Abstract: The Chappell Universal Square™ solves the problems associated with standard framing squares and provides a dynamic framing square bearing novel indicia and a novel arrangement of same for direct application to framing members during construction of complicated framing systems of equal and/or unequal pitched members.

The present invention is a tool that provides universal applicability for use in building both simple and complex structures according to metric and standard/imperial measurement systems. The present invention provides tabulated calculations aligned with indicia that enable construction of equal and complex unequal pitch framing members without necessitating the execution of complex trigonometric calculations.
