Crown 8-1/2" - 3

This creative 8-1/2" - 3 crown mould measures 8.486" width by .813" thickness enabling the use of four quarter lumber for machining on an industrial-grade molder. The grand supporting profile contains a 1-5/32" radius quarter round arc joined to a 17/32" vertical line segment on the top left. That section connects to a two tangent radius s-shaped curvature creating the cyma recta in the center with an additional 17/32" vertical drop in elevation. The remaining portion of the design consists of a 1-1/32" cove with a 9/16" horizontal fillet on the bottom right side 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 6" tall with a projection of 6" across the top.
