Crown 5" - 12

This deeply scooped 5" - 12 crown mould measures 4.993" wide by 1.375" thickness, requiring a 5-1/4" wide blank of six-quarter lumber for milling sprung (laying horizontally flat) on an industrial moulder. The symmetrical terminating profile comprises a 2-25/64" radius concave semicircle in the middle. The center attaches to a 1/8" line segment joined to a small two tangent radius ogee with an 11/64" line in the design's upper left and lower right corners. The spring angles are at forty-five degrees; the dedicated back bevels keep the face sides of the pattern parallel to the wall and ceiling. These specific angle positions lock in the installed height at 3-17/32" tall with a 3-17/32" projection across the top.
