One of the LARGEST cup style rain chains we offer – each cup is 4 1/2 inches across by 5 1/2 inches in length! For durability and strength, the connecting wires are made of stainless steel! Cups are made of pure aluminum, then powder coated our exclusive bronze color. This rainchain will handle heavy water flow conditions. A functional conversation piece for your home! To prevent damage in transit and reduce packaging volume, the upper wires are shipped un-assembled, so some assembly is required. It takes just a few minutes to assemble with no tools. Like all of our chains, comes with a V-hook for easy installation. You can also Increase water flow function with our optional Installation kit below which directs water from the gutter to the center of the chain for maximum efficiency.
