| *Minimum Ultimate Load
is 5 times the Working Load Limit. Based on single leg sling (in-line
load), or resultant load on multiple legs with an included angle less
than or equal to 120 degrees. ** Proof test load equals or exceeds the requirement of ASTM A952(8.1) and ASME B30.9-1.4 for the chain size and number of legs. †† Welded Master Link. |
