NIUNIU PREMIUM MATERIALS This swing harness is made of commercial grade polyethylene, our swing ropes can withstand harsh winters and harsh summers without fraying. 3 braided design provides better strong and reliable connection. Easy to install hanging, just throw the rope over the tree or beam and attach the hook to the swing or patio furniture; to adjust, open the safety catch, thread your marked length position through the 8 loops, lock and pull tight end of the rope. Most swings for high loads are secured with metal chains, but we recommend ropes as they are more comfortable to the touch and won't cause rust troubles. Each holds up to 660 pounds and is even stronger than those metal chains.
