Classica Ornamental Decorative Copper Downspout Bands. These are to fit 4″ and 6″ Round Copper Downspouts. Notice in the one picture that the depth (for 4″) is about 3/16″ greater than the downspout diameter. This added depth is to accommodate the Primary Mounting Strap that will actually mount the downspout to the wall. Same added depth for the 6″ as well.
