Crown Moulding 6-7/8"

This large colonial crown moulding 6-7/8" measures 6.875" in width by .625" in thickness and requires 7-1/8" wide blanks of four-quarter lumber for machining on an industrial moulder. The stylish profile comprises a 15/32" vertical line segment on the upper left. It connects to a 2-1/2" concave semicircle tangent to a 2-1/2" convex arc forming the cyma recta in the center. The s-shaped curve attaches to a 7/16" tall line merged with a 1-3/16" cove with a 1/2" flat line on the design's lower right side. The included spring angles are at forty-three and forty-seven 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 5" tall with a 4-23/32" projection across the top.
