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.
