Crown Moulding 4" - 9

Crown Moulding 4" - 9

This attractive crown moulding 4" - 9 measures 4.000" wide by .750" thickness. The gorgeous profile is comprised of a two inch radius cove in the center, attached to a 1/4" radius ovolo on top, the lower portion consists of a 1/4" radius arc joined to a cyma reversa with a 9/64" wide horizontal fillet on the bottom of the pattern.

The spring angles are fixed at thirty-eight and fifty-two degrees, these specific back bevels set the installed height at 3-5/32" tall with a projection of 2-7/16" wide. Three high points in the profile were intentionally positioned on the same level plane, our disciplined design features will assure excellent hold down conditions while milling the detail on an industrial moulder if the moulder pressure shoe is properly set parallel to the moulder bed plates.
