Purchasing the hardware from the Limbo Imports is the way to go. The key thing to remember is that the hardware must support "human weight" for safety. Most big box stores (Home Depot, Lowes, etc) had hardware but the packaging all said it was not designed for human weight. Finding all the right hardware is problematic. But the hanging kits from Limbo Imports had all the right items and was selected to make hanging easy as well as adjusting the swing height correctly. Overall great experience.
