KingChain Agricultural Safety Chain for Towed Machines is a required "safety backup" for tractor-to-implement connections. The safety chain maintains the connection between the tractor and the implement if the primary connection fails at any point. KingChain Safety Chains are made to the highest production and quality control standards and will work properly if and when they are needed. Manufactured from Grade 70 Transport Chain, one end features a 1/2" Clevis Grab Hook with a spring-loaded latch and the other has a 5-3/4" curved Grade 70 ring for the attachment loop to the drawbar or other attachment point. The chain has a permanent metal tag showing its weight rating, so there will never be any doubt. Safe Work Load (SWL) of 18,370 kg (40,500 lb). Never exceed the Safe Work Load (SWL). **NOTE** Do not use for overhead lifting.
