Rain Chains

Rain Chains

While the idea of a rain chain might seem relatively obscure to most of us, their history dates back centuries. Rain chains originate from Japan, where for hundreds of years, they have been used on temples and houses. The Japanese refer to them as “kusari doi” which literally translates into “chain gutter”.




A rain chain is simply a series of interlocking metal links which carry water from the roof gutters down into your My ECO Barrel™, a storage container, or a rainwater harvesting system. Functioning exactly like a drain pipe, this chain is attached to the end of a roof gutter to gently channel rainwater run-off from the gutter down to the ground. Usually, they carry links, hollow cups or funnels that produce a soothing sound as run-off hits them. This effective alternative to the conventional downspout can be easily integrated into a rainwater harvesting system by simply removing the downspout and replacing it with a chain.


Link designs are the closest to the original form. They tend to splash more than cup styles, and this may be important when they are considered for areas that are near doors, windows or walkways. From plain link chain to more fancy combinations of shapes, link chains offer the most open, airy look and clean lines. They are often used with modern architectural designs, but also look appropriate in rustic settings like cabins and log homes. The Zen Loops and Double Loops chains have the strongest Asian design influence. Cup designs are an improvement over links chains in performance and efficiency. With open bottoms, they act as funnels, focusing the water from one cup down into the next one. Even in heavy rainfall, cup styles splash very little, so they can be placed anywhere. Cups come in many shapes and sizes, from the cute 2in. Fluted Cups to the massive XL Scallop Cup, the largest cup style available. Climate LLC also has themed chains that include the popular Hummingbird rain chain, and many additional styles you can review in our catalog at the bottom of this page.
