6.0mm standard oval-shaped stainless steel quick link. Suitable for attaching a solo reserve parachute to the harness where the reserve, bridles and harness have narrow attachment points e.g. lightweight harness, lightweight reserve, Dyneema reserve bridles. Not suitable for wider attachment points as will squash up material, potentially weakening it. Can be used for the single point attachment between the solo harness and the reserve, or attaching the two harness reserve shoulder straps to the two ends of the reserve bridles (using two maillons).
