What makers wrote about this bin

  • I used it for my grow tent, holds nicely to the inside sleeve while attaching air duct to outside. Very thick material, highly durable and ultimately a great product!

    Luis · 5 of 5

  • I didn't measure it compared to the ac infinity ducting, and its not a great fit. That being said, it is well built and does not flex very much. If your duct isn't really close, you might have to get creative to make it work.
