This listing is for one (1) PVC Downspout Adapter. This adapter is made from Solid Core 4" PVC Schedule 40 pipe and accepts a 3"x4" corrugated downspout. It is 19" long but can be cut to length as needed and has 7" of internal travel for the downspout, making it ideal for the easy installing and uninstalling of the downspout. Because of the smooth transition to round pipe it provides less opportunity for clogging. Continental US buyers only!
