Crown 4-3/8" - 12

This primary 4-3/8" - 12 cyma crown mould measures 4.375" width by .750" thickness, allowing the pattern to be machined sprung (laying horizontally flat) utilizing four-quarter lumber on an industrial moulder. The attractive terminating profile contains a 1/2" tall vertical fillet on the top left. The line segment connects to a two-tangent radius s-shaped curvature (cyma recta) in the center with a 19/64" tall by 25/64" broad perpendicular line on the 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 3-5/32" tall with a projection of 3-1/32" across the top.
