perfect for connecting my downspout to a rain barrel! Also, give me the ability to divert around the rain barrel during winter!

The Flex-Drain ADP53102 Downspout Adaptor, Landscaping Drain Pipe Adapter 3 by 4 by 4-Inch downspout drain adapter is a great way to get two different size downspout sections to fit together. I used these for my commercial metal garage downspouts which are much larger than your standard gutter downspouts at home. I highly recommend these if you have different size downspouts that you are trying to connect. These also come in other sizes as well!

I was very disappointed in these. The 4" opening on the bottom DOES NOT fit other 4" fittings..even though the notches to snap into place are there. The plastic is also extremely flimsy. Even the 3x4" openings are all warped and dont hold their shape. Just really unimpressed by the quality and it doesn't fit other downspout extensions. Returned.

These aren't the greatest things in the world. They don't provide a tight seal. To wit, they link. Don't forget you need a connector piece to connect two pieces. Seems like it would be a better design to have one end female and one male, but what do I know. You also have to be She-Ra to extend the tubes. I think I burned all my daily calories just trying to get it extended. ...yeah yeah, that's what she said...they do the job, but not well.
