I don't know if these lengths of chain can be purchased from Amazon but this type and size of chain and hooks can be purchased from your favorite big box hardware store. My baskets are filled with dirt and hanging begonia plants and when filled with water, are strong enough to survive in the windiest of days so broken chains should not happen easily. Also, I place large size drip coffee maker filters inside the coco liners to help retain water for the plants to absorb.
