Crown 6-3/8" - 9

This extraordinary 6-3/8" - 9 crown mould measures 6.375" wide by .812" thickness, authorizing the use of four-quarter lumber for milling on an industrial moulder. The luxurious terminating profile contains a 15/64" vertical line segment merged with a 9/16" cavetto on the top left. This area joins a free-flowing 2-7/16" concave semicircle tangent to a 2-3/8" convex arc creating the cyma recta in the center, connected to a 5/16" tall line and another 9/16" cove with a 15/64" horizontal line at the bottom right side of the design. The fixed spring angles are at thirty-eight and fifty-two degrees; these particular back bevels keep the exposed face side of the profile parallel to the wall and ceiling when installed, as well as set the oriented height at 4-31/32" tall with a projection of 4" across the top.
