Abstract: A cable support device includes an arcuate mold having a cable channel with two ends for receiving an electrical cable and guiding the electrical cable around a ninety degree curve, the arcuate mold having an inner surface extending the full length of the arcuate mold and a partial outer surface located at each of the two ends of the arcuate mold. Retention clips having protrusions located opposite each other on the inner surface and the outer surface are positioned in the cable channel for holding the electrical cable in place. Inner and outer intermediate fastener guides having stepped members on either side of the arcuate mold are positioned on the arcuate mold to permit stacking of a plurality of arcuate molds. Fastener guides are provided at both ends of the arcuate mold to permit vertical to horizontal transitions.
