ABSTRACT OF THE DISCLSOURE A pump jack upright pole formed of an elongated metal pole having a rubberized surface formed on only one side of the metal pole. The pump jack securely rides up and down the pole. The rubberized surface is longitudinally offset with respect to the pole so that it extends past one end of the pole while exposing the opposing end of the pole. A splint is arranged to be received within adjacent ends of poles being spliced together with the rubberized surface extending end overlying the exposed pole end of the next adjacent section. The rubberized sections are inter- fitted to provide a continuity so that the pump jacks can ride up and down the poles without interference.
