PVC Dentil Header - Can be made using various sized backer board, PVC cornice or PVC Dentil strip.  PVC Headers are an excellent replacement for polyurethane being stronger and more impact resistant.

Made with trim board, 12 feet long available in various heights.  The parts include a smooth finished 12" PVC Trim Board, a  PVC cornice and a mid-sized PVC Dental strip.  The 12" high version comes with a 5" cornice, and the 10" and 8" comes with a 4" cornice.  Sizing is as shown on the drawing.  We leave the cornice separate to allow for hiding the mechanical fasteners to be used to mount header, the cornice is to be pinned in place after installation of the boards.  As an option, you may also add the base cap trim at the bottom.
