Adaptable

After searching around on the web, I finally located a rain chain adapter that fit the needs of the newly installed rain chain on the garden shed.

Made/sold by Stanwood Rain Chain via Amazon, the adapter is made of copper and should match the faux patina of the chain I purchased earlier this year. Most importantly, its large 4 1/5" top diameter funnels down to a 1 1/8" opening at the bottom. 

As a result, it limits the amount of splashing that was occurring near the top of the chain, and directs most of the water down along the chain and remaining cups. 

I very happy with this solution. It looks good and works as promised.
