Crown 3-5/16 - 12

This graceful 3-5/16" - 12 crown mould measures 3.346" width by .813" thickness, enabling a 3-9/16" wide blank of four-quarter lumber for milling sprung (laying horizontally flat) on an industrial moulder. The beautiful supporting profile comprises a 13/64" quarter round arc joined to a 15/64' vertical line segment on the top left. The line connects to a 1-3/32" concave semicircle tangent to a 49/64" convex arc forming an s-shaped curvature in the center, with a 1/4" tall by 3/4" perpendicular lines on the pattern's bottom right corner. The spring angles are at thirty-two and fifty-eight degrees; the dedicated back bevels keep the face sides of the pattern parallel to the wall and ceiling. These specific angle positions lock in the installed height at 2-1/2" tall with a 2-5/16" projection across the top.
