16B poly steel connecting links are also called 16B poly steel master links. The sole purpose of a connecting link is to connect two pieces of roller chain together simply; however, they can also be used as repair links. This connecting link is made specifically for 16B poly steel roller chains and is constructed of high-grade stainless steel. Something important to note, although dimensionally close to a standard 16B stainless steel connecting link, a poly-steel roller chain requires poly-steel connecting links to accommodate the additional pin length for the plastic roller links in a 16B poly steel chain.
