This is a patented flared cup rain chain designed by Garm Beall. These cups are powder coated black to match or accent your home decor. Lightweight and strong, this chain will last for many years. Powder coating is a type of coating which includes metal that is applied as a free-flowing, dry powder. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals. All cup styles are designed for the best water flow, even in heavy rainfall. Every chain comes with a 3" installation kit making it super easy to install!
