How to pick a rain chain installation kit

The Installation Kit you need depends largely on the size and shape of your gutters.

Rain chains are a beautiful and functional alternative to traditional downspouts, but to ensure they work effectively, you’ll need the right installation kit. This information will help you understand the differences between various installation kits so you can pick the one that fits your home best.

Standard Installation Kits vs. Half Round Installation Kits

Before anything else, identify the shape of your gutters, this determines whether you need a standard or half round installation kit.


Standard Installation Kits:

These kits are designed for K-style gutters, which are the most common type found on homes. K-style gutters have a flat bottom and a decorative front that resembles crown molding.

  • Best for gutters with flat bottoms
  • Commonly found in modern and suburban homes
  • Easy to identify by their angular, flat-bottomed profile

    Half Round Installation Kits

    These kits are made for half round gutters, which have a more traditional, rounded shape. Half round gutters are becoming more popular due to their classic aesthetic, especially in custom or historic-style homes.

    • Best for gutters with a rounded design
    • Often custom made or used in higher-end architecture
    • Recognizable by their rounded bottom

      Large Installation Kits vs. Regular Installation Kits

      Once you've determined the style of your gutters, the next step is measuring their size to choose between regular and large installation kits. It's also important to keep in mind that the Large Installation Kit is bigger than most rain chain cups, which may result in rainwater missing the first cup opening or chain link. Consider adding a Link Chain Reducer if this becomes an issue for you.


      Regular Installation Kits:
      • Designed to fit gutters between 2 ¾" and 4 ¾"
      • Suitable for most standard-sized gutters
      • Available in both standard and half round styles

        • Necessary for homes with oversized or commercial-style gutters
        • If you have half round gutters measuring 5 ½", you’ll need a Large Half Round Installation Kit
