Passable for Fixed Installation

Cheap compared to robust HVAC ducts that can be used in multiple locations. NOTE: slanted review by Global as lowest rating is FAIR. Really? The worst product possible is fair?

Passable for Fixed Installation

Your review: OK for a very fixed installation inside. It is NOT suitable for for anything that requires the ducts to survive sunlight or movement. Sun will destroy this product.

Pros: Cheap compared to robust HVAC ducts that can be used in multiple locations. NOTE: slanted review by Global as lowest rating is FAIR. Really? The worst product possible is fair?

Cons: Sunlight will destroy this product leaving only a skeleton of wire. NOT good for outdoor use. NOT good for over a short time. Ducts were not good for outdoor use on 3 locations before they deteriorated. Indoor and fixed locations only.

pretty good!

Your review: I needed duct to run the air from my whole house fan outside. It was quite a project for a 70 year old woman. And it took me a couple of days to do it. I like the quality of the product. It was important that it could be used with a lot of heat and with my 4700 air flow. Very happy I found something. Thanks

Pros: Hard to find a size that would fit my 18 1/2" diameter fan and the material I needed.

Cons: I was being careful but the wire started unraveling fairly easily. Could be my lack of experience.

HVAC Duct 20 inch

Your review: Excellent product and great price. I used it to hook up a ventilation system for my paint booth. Exactly what I needed via Global Industrial as I couldn't get the same product locally or at the best price.

Happy Overall.

Your review: I felt the price was slightly high and I would like to see a discount for buying in bulk, but overall I am impressed and would certainly order again. Thank you for making my order experience positive.
