King Chain 3/0 x 15 ft. Double Loop Chain
Double loop chain is weldless: each link is formed rather than welded shut. It is the chain used on playground and gym equipment, animal chains, padlock chains, boat chains and gate chains, where flexibility and low weight matter more than strength.
Weldless chain must never be used for overhead lifting or anywhere a load passes over people.

Questions
How much can it hold?
305 lb. working load limit.
What does weldless mean?
Each link is formed and looped closed rather than welded. It makes a lighter, more flexible chain, and a weaker one for its size.
Can I use it on a swing set?
Double loop chain is the type NACM lists for playground and gym equipment, but check the equipment manufacturer's own requirement before replacing anything a person will sit on.
When should I retire it?
Double loop and single loop chain should come out of service once wear or a change in material dimension goes past about ten percent.
Can I lift with it?
No. No chain in the weldless specification may be used for overhead lifting.
