When our solid MDF panel combined with our patented TruClose™ Spring hinges first hit the market in 1956 it became the top choice for Manhattan developers. From Turner Construction when they built the Hofstra Dormitories on Long Island to HRH Construction when they built The Trump Towers, developers have purchased our primed Bi-fold and Bypass doors to finish off all of their closet and pantry needs. Our flush bi-fold doors can be made to just about any size you require. Our standard bi-fold door is constructed of ¾” 45 lb. density MDF board and is available Primed, Prefinished-White, Espresso, Cherry and Unfinished Stain Grade Maple. We also offer a deluxe version of this door with a 1” panel. The doors in this family have matching trim, with both white and primed doors coming with white trim.
