High quality rain chain made of pure solid copper. The chain can replace traditional gutter while making soothing sound while rainwater travels. The copper construction is durable and will last decades while developing a beautiful greenish patina with age. The entire chain is 8-ft long and has 16 cups. This length is sufficient for a standard single story house. Each unit comes with an attachment piece and is very easy to be installed into your existing gutter system. Each cup is 3 1/4" tall, 3 1/4" in top diameter, and 1" in bottom diameter. Length of the chain can be easily adjusted by adding or removing cups.
