This door style has a 2-1/2" wide x 3/4" thick solid wood frame with a recessed furniture-grade plywood flat panel. It is an exact match to those on our mitered flat-panel style #1 (Jackson and Donovan) cabinets since it is made by the same manufacturer. Please note that doors taller than 39"H will require a third hinge and will be made with a horizontal divider and two panels for stability.
