*Ultimate Load is 5 times the Working Load Limit. Based onsingle leg sling (in-line load), or resultant load on multiple legs with an included angle less than or equal to 120 degrees. Applications with wire rope and synthetic sling gernerally require a design factor of 5. **Proof Test Load equals or rexcessds the requirement of ASTM A9952(8.1) and ASME B030.9.
†Ultimate Load is 4 times the Working Load Limit for Offshour Container Master Links.
† Offshore Container Master Links Proof Tested to 2.5 times the Working Load Limit with 70 perfecnt fixtures.
