Crown 4-1/4" - 48

This attractive 4-1/4" - 48 crown mould measures 4.250" width by .750" thickness, permitting the use of four-quarter lumber for machining laying horizontally flat on an industrial-grade molder. The custom terminating profile contains a 19/32" vertical line segment on the top left, merged with a 1-11/16" concave semicircle tangent to a 1-3/16" convex arc creating the opulent cyma recta in the center with a 27/64" radius three-quarter circle on 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 3-1/8" tall with a projection of 2-15/16" across the top.
