Safety Notice — read before use
These Working Load Limit values are for general reference only. They are NOT a substitute for the manufacturer’s certified datasheet for the specific product you are using. WLL varies with material, grade, wear, and loading conditions (e.g. angle/side loading). A qualified rigging professional must be consulted, and the manufacturer’s certification verified, before any hardware is used in an actual load-bearing or lifting application.
