Crown Moulding 4-1/2" - 20

Crown Moulding 4-1/2" - 20

This graceful crown moulding 4-1/2" - 20 measures 4.500" wide by .687" thickness. The lovely supporting profile is comprised of a 25/64" quarter round circle on top with a 11/64" tall vertical line, attached to a two tangent radius cyma recta with a 13/64" tall vertical line, joined to a 27/64" cove and a 3/16" wide horizontal line at the bottom of the design. The spring angles are fixed at forty-five degrees, these specific back bevels set the installed height and projection at an identical dimension of 3-3/16" tall and wide. Two high points in the detail were deliberately positioned on the same plane, our disciplined design features will assure excellent hold down conditions while milling, providing the moulder pressure shoe is parallel to the machine bed plates.
