Crown Moulding 8-1/2"

Crown Moulding 8-1/2"

This elegant cyma recta crown moulding 8-1/2" measures 8.500" wide by 1.250" thickness, requiring six quarter lumber to mill this design on a industrial style molder. The graceful profile is comprised of a 2-5/8" arc, tangent off of a 3-3/16" curve creating a cyma recta in the center of the design, connected to a 57/64" tall vertical line on the top. The lower portion of the design consists of a 57/64" tall vertical line, attached to a 1-7/16" wide horizontal line forming a squared fillet at the bottom of the pattern. We have a big group of similar style profiles with different widths, heights and projections, here are just a few sizes you may want to review and consider for your next home project, crown molding 1.500" - 9, 2.000" - 6, 2.500" - 1, 3.000" - 19, 4.000" - 1, 5.500" - 44 and 7.000" - 3.

The spring angles are fixed at thirty-eight and fifty-two degrees, these specific back bevels set the installed height at 6-1/2" tall, with a projection of 5-1/2" wide. Two high points in the design were deliberately positioned on the same plane, our exceptional design features will assure superior hold down conditions while milling the detail on an industrial moulder, providing the pressure shoe is parallel to the moulder bed plates.
