High-quality rain chain made of pure solid copper. The chain can replace traditional gutter while making a 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.
