Crown Moulding 7" - 9

This sumptuous crown molding 7" - 9 measures 6.990" width by 1.000" thickness requiring the use of five quarter lumber for machining sprung (laying horizontally flat) on an industrial-grade molder. The free-flowing terminating profile contains a 5/16" vertical line segment on the top left. The short line connects to a 2-13/64" concave semicircle tangent to a 2-19/64" radius convex arc forming the center's cyma recta. The lower portion retains a 3/4" radius convex arc tangent to a one-inch concave semicircle creating a cyma reversa with a 17/64" flat line on the design's 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 5-1/2" tall with a projection of 4-5/16" across the top.
