The Steel Cups Rain Chain is made with stainless steel for greater strength, durability and value pricing. Each cup links to the next cup for optimal water flow. This rain chain functions beautifully in all rainfall conditions.How Rain Chains Work Rain Chains are decorative replacements for downspouts and are required to be used in conjunction with gutters. To install, remove your current downspout and place the included installation kit in the hole in your gutter. We recommend using an all-weather caulk as well. Hang your chain off the bottom of the installation kit so it hangs directly down and ensure you purchase enough length to reach the ground. It is very important to secure your Rain Chain to the ground with a decorative pot or stake to prevent it from swaying in the wind. It is important to note that rain chains cause slight amounts of splashing in rainstorms but not enough to effect the function of your gutters.
