1. In combination: an upright utility pole having a vertical axis and a diameter; an aperture formed through the pole; a tubular sleeve journaled through the aperture and projecting from opposing sides of the pole; a crossarm extending through the sleeve and having free opposing ends projecting from opposing sides of the pole; and means for removably fastening the crossarm to the sleeve. 2. The combination of claim 1, wherein the aperture and crossarm are oriented generally perpendicularly to the pole vertical axis. 3. The combination of claim 2, wherein the aperture and crossarm pass through a central axis of the pole. 4. The combination of claim 3, wherein the pole is a tubular member and the aperture includes an opening formed in opposing walls of the pole. 5. The combination of claim 4, wherein the sleeve has a cross-sectional shape which is the same as a cross-sectional shape of the crossarm. 6. The combination of claim 5, wherein the crossarm is an elongated tubular member. 7. The combination of claim 6, wherein the crossarm has a rectangular cross-sectional shape with a vertical axis greater than a horizontal axis. 8. The combination of claim 7, wherein the means for removably fastening the crossarm includes a pair of bolts journaled through pairs of diametric apertures in each sleeve projecting end and pairs of diametric apertures formed in the crossarm. 9. The combination of claim 8, wherein said pole and sleeve are metal, and wherein said sleeve is fastened to the pole by welding. 10. The combination of claim 1, wherein the pole is a tubular member and the aperture includes an opening formed in opposing walls of the pole. 11. The combination of claim 10, wherein the sleeve has a cross-sectional shape which is the same as a cross-sectional shape of the crossarm. 12. The combination of claim 1, wherein the crossarm is an elongated tubular member. 13. In combination: an upright tubular metal pole; a generally horizontal aperture formed through the pole and extending though a central vertical axis of the pole; a tubular metal sleeve journaled through the aperture and fastened to the pole with opposite ends projecting outwardly from the pole; a tubular metal crossarm journaled though the sleeve, with free opposite ends projecting from the pole; and means connecting the crossarm to the sleeve to prevent movement of the crossarm relative to the sleeve and pole.
