Jack chain
Jack chain may be manufactured as either single-jack chain or as double-jack chain. If double-jack, the lower loop is formed of two strands of wire rather than just one as in a single-jack. Before the days of lavatory cisterns being close to the pan, jack chains were often used to release the cistern plug.
