Unlike other crown molding jigs on the market, the Crown King requires no assembly and is designed for the ultimate ease of use. Right out of the box, it enables professional and DIY woodworkers to produce interior and exterior corner joints with the three most common crown molding spring angles (38, 45, and 52 degrees). The Crown King comprises two pieces: the jig itself and a versatile and reconfigurable insert/adapter. Without the insert, the jig is positioned for cutting 45° spring angle moldings. The insert quickly reconfigures the jig to accommodate 38° or 52° spring angles. In combination with a miter saw, the Crown King can create precise joining angles every time. Simply measure the corner angle, divide it by half, set your miter saw to that angle, cut and fit. No complicated compound miter angle calculations are necessary. The jig further simplifies the creation of crown molding by eliminating coping of joints, compound-angle cutting, back-cuts, and auxiliary fences.
