A fall protection device for an opening in a roof includes at least one rail section having a vertical member. The vertical member is preferably in the form of a metal tube having an open lower end. A bearing foot has a connecting portion and a bearing portion and is secured to the lower end of the vertical member by the connecting portion so that the bearing portion supports the vertical member above the roof. The connecting portion of the bearing foot preferably extends into the open lower end of the tube and resiliently engages an interior surface of the tube to secure the bearing foot thereto. A hardness of the bearing portion is greater than a hardness of the connecting portion. The connecting portion and the bearing portion are preferably plastic and co-molded so that the bearing foot is of unitary construction.
