The XL Aluminum Scallop Cup rain chains are one of the most popular rain chains on the market.  Each cup is over 4" wide and 5 1/2" tall and can handle a large amount of rainfall.  The 1 1/2" opening at the bottom is not much smaller than a standard size downspout.  The clips connecting each cup together are made from a heavy grade of stainless steel for extra strength and durability.      

Every XL Scallop Cup rain chain comes with a free gutter attachment piece that rests inside the gutter that attaches to the rain chain.
