Non-metallic rigging chain formed with a plurality of linked flexible loops. Each loop has a core which consists of a continuous strand of non-metallic materially coiled upon itself. The coiled core material is sheathed within a woven outer fabric. Except for the two terminal loops of each chain, one loop is formed by coiling a continuous strand of core material in linked relation within a pair of completed loops. The length of each chain is determined by the diameter of its loops and the number of loops linked together.
