Using this product to carry heat from horticulture lights away from the growing area into the processing cooling section. We have a 4 inch on top of each light with its own fan. so I'm growing units we have two fans on as what's growing inside we're trying to keep it at 70 or cooler this means refrigerated air pumped in hot air pumped out lots of tubing lots of clamps. we have a mismatch from different manufacturers vivo sons clamps are better than others but they're tubing is a little thinner it's all Chinese it's all hit or miss and it's all within a couple of dollars of one another if you're not needing heavy duty insulated this product will work just fine if it's up out of traffic. this product isn't sturdy enough to have interaction with things on a regular basis it will slice or tear.

These are exactly as described. For $15 I got two of these in a box. At my local big box store they were 16 bucks just for one. The metal sheeting is thick and durable. Sometimes when you attach these to the connectors the foil will tear but these didn’t tear at all and went on great. It came with four screw down clamps which was awesome it saved me a trip to the store. They went on easily and cinched down tight without breaking. Awesome value and great performance I’d buy them again when I need them.

The old duct was disconnected from the vent into the 1st floor bathroom and the original ducting did not appear to every work. So I cut off about two feet of the flexible ducting, slid one end over the vent part, used aluminum tape to fasten inside and outside of the old vent and flexible vent. Next stretched out to slide over the existing vent and again applied aluminum tape. This took about one hour. An HVAC quote was $400 and my cost less than $10!

Great price for good quality product. I was looking for something inexpensive to finish my Tesla coil toroid (the part shaped line a wheel that shoots sparks) 2 dollar tree pizza pans separated buy cleaned out wet cat food cans wrapped in this aluminum duct worked beautifully. I work with aluminum duct work in diesel heat&a/c systems all the time, this is much sturdier. Very solid product.

This ducting hose is actually of very impressive quality for the price. I really honestly don't have anything to say besides how much I am impressed by the fitment, the seal, and the strength of this stuff. The stuff I was looking at when I went to Home Depot was more expensive, and of lower quality.

I don't know what drops the price on these but I didn't detect any tears which I think is really ALL that matters. If there are tears, they shouldn't sell them. Under $14 for the pair is a pretty good price I thought.

i have a room under my house, the air flow was only coming from the hatch floor entrance and i needed to get more air flow so i got this and some fans to bring more air in and the tubing was flexible enough to get it between the bars in the little window, the air flow is great and the kids love it.
