MOUNTO 25FT PVC Flexible Duct Hose for Exhaust Fan - 18 Inch Diameter, Heavy Duty Ventilation Pipe for Dryer, HVAC, and Grow Tent Airflow - Perfect for Home, Garage, and Industrial Ventilation Systems

So far this 8 inch duct hose is by far the best that one can get for the money, I put off a couple of years of not buying one for my confined space blower, The only thing I regret is not buying 2 at the same time, For the money saved I should have bought 2 of them. The bad is mostly on my part, My confined space intake does not have a large enough lip on it to attach the hose, The attachment sits back a little over 1 or 2 inches making it hard to attach to a small lip. Yet it works good on the exhaust part. The length works out pretty good for most projects. Right now I have it blowing air from the first floor to the second floor via the old chimney hole as the blower is quite heavy to move up and down the stairs every day. The D rings are great as you can use hooks, nails or just about anything to attach it to place it where you want. So far I have used it for almost a month in a nail infested remodeling of a older house. The vinyl that it is made of seems like it should last many years, My only concern is that over time UV and brittleness will set it and the hose will start to crack on the bends and flex parts. The wire inside is pretty strong and will hold up to most abuse, I have bent one of them and just a little bit of flex its back to the original shape.Would I buy again...
