Apparatus for converting automobile roof top surfboard carriers of the type that has a pair of roof spans in parallel relationship fastened in the rain gutters, into ski carriers. A conversion unit having a metal tube with crimped ends, with several apertures for pin mechanisms in those ends, is bolted to each roof span. The metal tube has a U-bolt fastened at its center. A strip of hot rolled mild steel is slideably attached to each leg of the U-bolt. The strip of steel has a plate depending from one end. There are several apertures for pin mechanisms in the plate. The strip of mild steel has lengthwise shallow bow which is about one and a half inches deep at its maximum depth. Between the plate and the U-bolt aperture, a strip of high density rubber depends from the bow. The operator spreads the skis over the metal tubes of the roof spans and under the bowed strip of steel. He presses down upon the plate. The bows flatten over the skis. They become partially embedded in rubber. The bowed steel strip moves up its leg of the U-bolt and jams to a halt. The operator slides padlock shackle or a pin mechanism through the apertures in the crimp and in the plate, whereupon the skis are clamped upon the roof spans and remain so until the operator removes the padlock or pin mechanism.
