T.M.Cobb includes French doors in an arched top rail and common arched pair designs, which complement our premium MDF series. These doors are assembled with a durable MDF veneer lamination over pine core stiles and rails. Built with our customary stile and rail construction and a true divided lite (TDL) with 1/8” press fitted tempered glass. Each pane has a protective film covering the glass. Each door is delivered with two coats of acrylic-base latex factory applied primer. Each door is sanded between each primer application.
