Rain chains make beautiful alternatives to traditional downspouts. They guide rainwater from gutters to the ground along chains, cups or other designs, which creates an aesthetically pleasing effect. Rain chains transform a plain downspout into a pleasing water feature. Like downspouts, rain chains prevent water from just falling out of a hole in your gutters and onto the ground, which can cause erosion and splashing. Instead, they break water flow and create a softer, more streamlined landing.
