Crown 4-5/8" - 15

This incurved 4-5/8" - 15 crown mould measures 4.641" width by 1.000" thickness, requiring the use of five-quarter lumber for milling sprung (laying horizontally flat) on a commercial-grade molder. The terminating concave detail contains a 13/32" vertical line segment on the top left. The fillet connects to a 2-9/16" cove with a 3/16" horizontal flat section merged with a 3/16" radius convex arc tangent to a 5/16" concave semicircle, creating the ogee and a 3/16" broad flat line on the bottom right side of the design. The set spring angles are at forty-five degrees; these dedicated 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 3-3/8" tall with a projection of 3-3/16" across the top.
