Crown 3-5/16" - 13

This stunning 3-5/16" - 13 crown mould measures 3.319" width by .687" thickness, requiring a 3-9/16" wide blank of four-quarter lumber for milling sprung (laying horizontally flat) on a commercial moulder. The attractive terminating profile comprises a 15/32" tall line segment joined to a 5/16" tall by 1/4" wide notch on the top left. The cut-out connects to a 1-1/16" concave semicircle tangent off a 3/4" convex arc, creating the free-flowing cyma recta with a 3/16" high line in the center. The short line joins another perpendicular notch with an 11/32" broad line on the design's bottom right corner. The fixed spring angles are set at thirty-eight and fifty-two degrees; these particular back bevels keep the face side of the profile parallel to the wall and ceiling when installed, in addition to locking in the height at 2-5/8" tall with a 2-1/32" projection across the top.
