Crown 8-1/2" - 4

This sophisticated 8-1/2" - 4 crown mould measures 8.507" width by 1.000" thickness, necessitating using five-quarter lumber for machining on an industrial moulder. The grandiose terminating profile contains a shallow cyma recta flanked by vertical line segments on the top left. The vertical fillet merges with an 11/16" concave semicircle and a 13/64" bead connected to a 2-1/2" radius convex arc with a 17/64" vertical drop in elevation in the center. The remaining portion of the pattern consists of a 1-3/16" concave semicircle joined to an additional bead with a 39/64" radius cove bordered by a 7/32" vertical fillet above and a 1/4" horizontal fillet on the bottom right corner 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.
