Crown 5" - 30

This enthralling 4" - 30 crown mould measures 4.000" width by .813" thickness, allowing the use of four-quarter lumber for milling on a commercial moulder. The asymmetrical supporting profile contains a 15/32" radius convex arc, joined to a 7/32" tall vertical fillet on the top left. The center consists of a two tangent radius cyma recta with a 5/16" tall line segment, this area merges a half-inch radius ovolo flanked by a 17/64" horizontal line on top and two perpendicular lines at the bottom of the design. 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 3-1/2" tall with a projection of 3-9/16" across the top.
