Crown Moulding 4-1/4" - 61

Crown Moulding 4-1/4" - 61

This intricate crown moulding 4.250" - 61 measures 4.250" wide by .750" thickness. The stylish profile is comprised of a 1/4" wide half round bead merged with a 49/64" concave semicircle on top, joined to a 1-29/32" radius arc in the center attached to a 9/64" vertical line, connected to a 3/8" cove with a 1/8" wide horizontal line and a 1/4" quarter round circle at the bottom of the design. Be sure to check out a few other profile designs for different rooms in your beautiful home, our moulding catalog has over fifteen thousand profiles to select from.

The spring angles are fixed at forty-five degrees, these specific back bevels set the installed height at 3" tall with a projection of 3" wide. Read our commentary about axial constant positioning for crown bevels, the article will help you dial this profile in axially on the first try when milling this detail provided the machine is axially calibrated. Two high points in the detail were deliberately positioned on the same plane, our specialized design features will assure excellent hold down conditions for milling, providing the moulder pressure shoe is parallel to the machine bed plates. Using felt on the bottom of the pressure element will help eliminate any unsightly burnish mark that may be left on the beads of the profile from the hold down unit.
