I had a REALLY hard time finding replacement parts for my downspouts. They are RainMaster, by Bemis. But, Bemis doesn't make them anymore. They sold off that part of the company. But, I *finally* found out who bought it... Amerimax.

They were special order parts through the local big box hardware store. I hear they are phasing them out, but the are still available (I just picked my order up today). I had to order 6 pieces of 2" x 2" x 10 ft. white vinyl downspout, but at least I can get them (don't know for how much longer, though).

I didn't find much on the Rain Master system when I did a web search, so maybe it will be easier for people to find now.

Cheers!

 

2" square downspouts won't handle much water. Hopefully by the time these wear out, or you get tired of the gutter overflow, you can install 5" gutters with 4" downspouts, which should handle the water quite well.
