Crown 4-3/8" - 9

This delightful 4-3/8" - 9 crown mould measures 4.376" width by .750" thickness, enabling the use of four-quarter lumber for machining sprung (laying horizontally flat) on an industrial moulder. The relatively modest profile contains a 1/2" tall vertical line segment on the top left. The line attaches to a 1-3/16" radius concave semicircle tangent to a 2-3/32" convex arc, creating the center's cyma recta. The lower portion retains a 9/32" vertical line merged with a 3/8" horizontal segment and a 7/16" tall by 1/2" full perpendicular line on the design's bottom right side. 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 3-3/32" tall with a projection of 3-3/32" across the top.
