Rain chains also known as "kusari
doi" after their Japanese name, originated
in Japan and are alternatives to the downspout component
in a traditional rain gutter system. Their purpose
is both decorative and functional - to make a water
feature from the transportation of rainwater cascading
downwards into a drain or to a storage container.
(Rainwater, collected for household usage has now
been given the new name - Water Harvesting.)
chain are typically either a series of metal
cups, linked together with a hole in the bottom
of each, or chain links that span vertically.
Rain chains originated in Japan hundreds of years
ago. They work exactly like American downspouts,
but in a way that evokes pleasure and delight. What
makes rain chains so unique is that the water falling
from the roof is actually seen instead of being
contained and drained away. Rain swirls and flows
down, creating a mesmerizing sense of motion and
tranquility right outside your window. The rain
chain works by breaking the fall of rainwater, which
adheres to the chain due to surface tension. It
is a perfect way to divert the water off your roof
either into a rain garden or rain barrel. The beautiful,
pure copper rain chain adds an architectural accent
to your home exterior. Over time the copper develops
a rich green verdigris (or patina), creating
an attractive "antique look".
There is a possibility of damage to the cup style
rain chain in areas of heavy snow. We recommend
you take the rain chain down during a big snowstorm
to prevent break down of your rain chain.
In areas of heavy snowfall we recommend you use
the Link Rain Chain.
