Crown Moulding 3-1/2" - 12

This stylish crown moulding 3-1/2" - 12 measures 3.500" wide by .688" thickness. The graceful profile is comprised of a 31/64" tall vertical line on top, connected to a two tangent radius cyma recta in the center, the lower portion consists of a small stepped fillet connected to a two tangent radius cyma reversa with a 13/64" wide horizontal line at the bottom of the pattern. We have a slightly larger version of this detail for your review and consideration, crown moulding 3.750" - 6.

The spring angles are fixed at thirty-eight and fifty-two degrees, these specific back bevels set the installed height at 2-27/32" tall with a projection of 2-3/64" wide. Two high points in the detail are intentionally positioned on the same level plane, this helpful design feature will assure excellent hold down conditions while milling the detail on an industrial moulder, providing the pressure shoe is set parallel to the bed plates. Take advantage of our specialized design skills, over thirty years of experience in wood moulding manufacturing, superior designed acrylic templates, and exceptional quality custom moulding knives.
