Crown Moulding 7-3/4" - 5

This gorgeous crown molding 7-3/4" - 5 measure 7.759" width by 1.250" thickness requiring the use of six quarter lumber for machining sprung (laying horizontally flat) on an industrial-grade molder. The distinctive terminating profile contains a 23/32" tall by 3/8" broad perpendicular lines joined to a small ogee on the top left. The center consists of a 2-59/64" radius concave semicircle merged with a 55/64" wide by 1-3/32" tall notch, attached to a 3/4" ovolo with a 33/64" flat line on the bottom right side of the design.
