If you have a big, beautiful tree from which you'd like to hang a swing, check out our Rory's Tree Swing option. This comes with all necessary hardware to attach a swing to your tree, including the seat, eyebolts, chain, and chain loops to go around the tree limb. We recommend you use an old garden hose to wrap around the tree limb. Slice it open lengthwise and place the chain in it. Don't wrap the chain tightly around the tree limb. Give the limb some growing room. Our standard length of chain is 10 ft, plus 3 ft for the loops. But let us know at checkout if you need more or less, and we'll be glad to send you exactly the length you need.
