*New Rope Tensile Strengths are based on tests of new and unused rope of standard construction in accordance with Cordage Institute Standard Test Methods.

**In accordance with Cordage Institute Standard Test Methods, working loads are for rope in good condition, with appropriate splices, in non critical applications, and under normal service conditions.  As a general rule, safe recommended working loads are 10%-15% of new rope tensile strengths.

This weight, strength, size and working load chart supersedes all data and specifications sheets published prior to June 1, 2000.
