Copper Offsets, also called ledge jumpers, are used to bring a downspout out and around a ledge on the wall. We carry copper offsets for 2" x 3" and 3" x 4" rectangular copper downspouts and also for 3" and 4" round copper downspouts. Our offsets work on ledges ranging from 2" to 5". All of our copper ledge jumpers are made from 16 oz. copper.
