Minimum breaking strength in tons of 2000 lbs.
Actual strand construction varies by size.
For example, 1/2-1"" is 1x19.

Warning: Wire rope & aircraft cable should never be used at breaking strength. 10:1 safety factor minimum is recommended for critical/overhead application. Do not use for overhead lifting without consulting a wire rope rigging professional. End fittings may not hold to 100% of strength efficiency so a safety factor such as 5:1 should be divided into the assembly actual strength. A pull test is recommended for quality assurance.
