Crown 5-7/16" - 1

This standard 5-7/16" - 1 crown mould measures 5.454" width by .812" thickness, allowing a 5-11/16" wide blank of four-quarter lumber for milling sprung (laying horizontally flat) on a commercial moulder. The standard terminating profile comprises a 39/64" vertical fillet on the top left. The line connects to a graceful cyma recta derived from a 1-1/4" concave semicircle tangent off of a 57/64" convex arc in the center. The lower section contains a 1/2" vertical line segment joined to a 3/4" cove with an 11/16" horizontal fillet on the designs bottom right side. The fixed spring angles are set at thirty-eight and fifty-two 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 4-3/16" tall with a 3-1/2" projection across the top.
