Means are also included on the outer face for mounting the door in operative communication with biasing means to place a con- tinuous biasing force against the door at least when it is in a closed position. The inner face of the door includes knife- edge like sealing means protruding outwardly therefrom for sealing the door when it is in a closed position. The con- figuration of the knife-edge sealing means is such to enhance leveler door sealing during a coking operation.
