Our Link Style rain chain comes in 10-foot sections with 34 large interlocking rings and 34 smaller rings per 10-foot section. Link Style rain chains can be made shorter or longer by cutting and soldering together extra interlocking rings to the top or bottom of the rain chain. The Link Style rain chain consists of two interlocking rings that are 2-7/8″ in diameter, and each large interlocking ring is attached by a smaller 1-1/2″ ring. Heavy duty solid 3/16″ thick copper wire is used to make each ring, which are then fully soldered together. Each rain chain comes with a piece of heavy duty wire for attaching to the gutter.
