Cable size          Ultimate breaking strength

3/16"                        3,990 pounds
1/4"                          6,700 pounds
5/16"                       11,200 pounds

These representative figures are for EHS and some types of galvanized and
stainless steel aircraft cable.  Consult the manufacturer for exact
specifications.
