Important: The manufacturer’s published figure is a breaking load, not a stated Working Load Limit (WLL). Therefore, this particular shackle should not be specified for lifting applications based solely on the 950 kg breaking-load figure. For certified lifting, use a shackle specifically rated and marked with an appropriate WLL and applicable lifting standard.
