Abstract
A substantially plastic ladder chain is made continuous by affixing the exposed metallic cable ends thereof to a master coupling link of stainless steel or like material. The exposed metallic cable ends of the plastic ladder chain comprising plural braided cable also of stainless steel or like material are fastened in such a way to separate master cross links, of the aforementioned master coupling link, by master link side lock pins of brass or like material so as to form substantially a molecular bond. The master cross links are then connected together in a conventional manner by master link retainer clamps and master link retainer clips, thus forming the continuous ladder chain.
