You can order 4-panel doors in White or Oak, Walnut, or both. We also offer prefinished doors. The traditional 4-panel door has 4 rectangular panels and two longer panels above a horizontal center rail. There are two shorter panels below the horizontal center rail. The 4-panel doors also come in a “contemporary” style. This is where the panels or glass are equal in height but are separated with horizontal “astragals”, or “rails”.
