This attractive crown moulding 8" - 20 measures 7.986" wide by 1.062" thickness, permitting the pattern to be milled sprung (laying horizontally flat) out of five quarter lumber. The stunning terminating profile is composed of a 13/16" tall vertical line segment on the top left, attached to a smooth two tangent radius cyma recta, joined to a 5/32" wide by 15/32" tall perpendicular lines in the center, attached to a 47/64" high convex semicircular arc, merged with a 7/32" tall fillet and a 1/2" cove with a 15/32" wide flat line on the bottom right side of the design.
