Our Bluebell Cup Rain Chain is a truly unique style. Original in it's design, it is a combination of both the Bell Cup and Traditional style Rain Chains. Between the two cups are links made of 2 traditional loops as shown in the picture. Each Bluebell Cup is 3 1/4" tall, has a 3 5/8"W top diameter, and 3/4"W bottom diameter. 4 Foot Rain Chain Extensions are available in both styles. The length of the chain can be easily adjusted by adding or removing bells. The installed Rain Chain is about 8' long and has 10 Bluebells Cups. This length is sufficient for a standard single story house. Each Rain Chain comes with an attachment piece allowing you to easily install it into your existing gutter system. All of our Rain Chains are made of 100% pure solid copper and will develop a beautiful greenish patina with age. The copper construction will make the chain last for decade..
