Abstract
A means for guiding a coke oven door as it is replaced on an oven. The guide means includes bars carried by the door frame for guiding the door accurately to a position in which the sealing members contact a flat surface on the jamb to effect a seal. The forward tips of the guide bars are closely adjacent the forward edges of the sealing members so that the guide bars serve also as stops to prevent overloading of the sealing members.
