Simple rain drainage chain on a canopy

A rain drain chain or rain chain is attached as a decorative water feature or kinetic sculpture between the gutter / funnel and the water drain or collection container. It replaces alternatively, the rainwater - downpipe and gives a clear view of the the chain links following raindrops .


Japanese rain chains "Kusari Doi" ( Japanese:鎖 樋) have been known and loved for centuries at temples and houses with their relaxing and calming effect on the observer. As a visual embellishment of a dull rainy day, as well as the splashing of rainwater offers a "music" that promotes peace and quiet, which Buddhism and Japanese Zen strive for.

Shape and material

Chain with cup-shaped funnels

The appearance of the rain chain depends on the material of the chains. It can be made with different shapes and sizes, from simple plastic chains, galvanized or rustproof chains, from copper, aluminum or brass. Other possible add-on or intermediate components such as bowls, funnels, goblets or copper lotus blossoms and other artistic cones serve the centering drainage and the optics .


However, continuous drainage is no longer entirely possible in heavy rain , splashing occurs around the rain chain, so it should not hang down directly near building walls. The rainwater should have a large area that is secured with stones / pebbles for drainage, otherwise the surrounding soil will soften. (Slipping).
