Crown 4-5/8" - 12

This conventional 4-5/8" - 12 crown mould measures 4.640" in width by .750" in thickness, allowing 4-7/8" wide blanks of four-quarter lumber for milling sprung (laying horizontally flat) on a commercial molder. The long-established terminating detail contains a 9/16" vertical line on the top left. The tall line segment connects to a 2-9/64" concave semicircle tangent off of a 1-33/64" convex arc, creating the center's graceful cyma recta. The s-shaped curvature attaches to a 13/32" tall by 33/64" broad perpendicular lines 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 3-5/16" tall with a projection of 3-1/4" across the top.
