A universal coke oven door for use on varying width oven chambers in a coke oven battery is formed with hot side refractory sections and cold side refractory sections spaced therefrom. Ceramic wiper strips are provided which extend outwardly from the sides of the hot side refractory sections towards the oven doorjambs to prevent passage of coal or coke between the hot side refractory layer and the doorjambs. Sole plates may be provided on the bottommost refractory sections of the hot side or cold side refractory layers, while an extension is provided on the topmost refractory section of the hot side refractory layer which extends towards the cold side refractory layer and prevents coal or coke from entering the spacing between the two refractory layers.
