Aquabarrel 4x6x4 Downspout Adapter (White) 2 piece Adjustable Universal Fit to 4inch Round Drain Pipe

Works perfect, delivered as expected.

The item fits properly and does the job, however, it is a little flimsier than I expected and the 4" section is smaller than 4" but has extensions on the outer diameter to allow a snug fit with the 4" pipe. This adaptation probably makes it easier to insert into the receiving pipe. Overall, I certainly would buy the item again.

Severely reduces the flow of water. Needs better design. Had to go back to a job remove and replace these with another product.

Had a hard time finding this size locally, and this saved the day. I have a downspout just outside my garage door that causes water to pool up in the garage. With this adapter I was able to attach a 4" hose to re-direct the water and keep my garage dry.
