All of our rain chains come pre-packaged at 8.5' in length with the exception that 8 of our styles we offer 3' extensions (view 3' extension tab). If you need extra footage of a style we do not offer a 3' extension on you would need to purchase additional chains to accomadate the footage needed. Add what you need and remove what you do not need. All styles can easily be made longer or shorter. This is something you would do before you install them.
