* Knots and abrupt bends significantly reduce the strength of all ropes and lower maximum working load.
** Working load is based on static or moderately dyanmic lifting/pulling operations. Instantaneous changes in load, up or down,
in excess or 10% of the rope’s related working load constitute hazardous shock load and would void the normal working-load
recommendation. Consult Yale Cordage for guidelines for working loads and the safe use of rope.
