General Tool & Instrument's EZ Pro Crown King

No assembly is required to use this crown molding jig from General Tool & Instruments, which allows easy creation of interior and exterior corner joints with the three most-common crown molding spring angles. An included insert/adapter can reconfigure the jig for 38- or 52-degree spring angles; without the insert, the jig is positioned for 45-degree cuts. The tool can be used in combination with a miter saw for the most accurate joining angles.
