SIRIUSHAIR MANUFACTURED REPLACEMENT CABLE RING These cable rings are fitted to the GHD 3.1B model of hair straightener, unfortunately after time the rubber rings perish or are damaged whilst removing, this seriously affects the integrity of the GHD cable connection leading to damage to the plastic body and cable.
