We have rain chain installation kits available in copper and aluminum. They come in 3" standard length or an extended 6" length. Most gutter openings allow for the copper or aluminum tube to fit through the opening for a nice fit. You may want to use a little silicone caulk for an added seal. Installation kits are recommended for a nice finished look to your rain chain installation and help direct the water on to your cup or link style rain chain. All installation kits are nicely crafted and we offer free shipping.
