Working Load = Breaking Load divided by 4 eg (1/4 Dia B/L 5200lbs W/L 1300lbs 4:1)
Breaking Load is determined by applying an increasing tension (not Shock Loading) to the chain until chain failure
The safe working Load (W/L) is determined by your application. Some applications may require a different W/L
This Proof Coil Chain is NOT designed for overhead Lifting
