Crown 4-3/16" - 9

This stunning 4-3/16" - 9 crown mould measures 4.202" wide by .750" thickness, requiring the use of a 4-7/16" wide blank of four-quarter lumber for milling sprung (laying horizontally flat on a commercial molder. The impressive terminating profile contains a 13/64" vertical line segment joined to a two tangent radius cyma recta on the top left. The s-shaped curvature connects to a 9/64" tall line merged with a 9/32" cove in the center. The remaining portion of the pattern consists of a 1/2" wide by 45/64" tall perpendicular notch connected to a graceful ogee flanked by horizontal fillets on the design's bottom right side. The fixed spring angles are set at forty and fifty degrees; these particular back bevels keep the face side of the profile parallel to the wall and ceiling when installed; they also lock in the positioned height at 3-1/8" tall with a 2-13/16" projection across the top.
