8"×16.4FT PVC Flexible Duct Hose, Flame Retardant HVAC Ducting with Adjustable Rope, D Hook & Steel Support for Ventilation, Exhaust, Drying, and Cooling Applications

We bought this to make a rabbit hole behind the sofa for our pet rabbit. It worked great. He does like to chew it up, but it's his so that's alright. It was worth the money

Better price than the big box stores and the shorter length I wanted

As described, feels sturdy also

Useful

melted but i guess it did not catch fire

Got this for temporary ventilation. Not disappointed - has a drawstring on one side to attach, has several D rings along length, somewhat sturdy material (kinda like a very thin and cheap tarp). Collapses to like 6in thick which is nice, glad I didn't buy the expensive bags other people were selling. When you get it has an awful chemical smell. I ran it outside for several hours with my fan, and the smell reduced. After a few days it became very slight. Also, my toddler loved going through the tunnel (with the fan disconnected, obviously). It's not child safe at all, they get trapped in it, and there might be some bits of wire or whatever that pop off - but seemed fun though.

Good quality!

Generous 25 foot section of 12 inch PVC flex hose. Reinforced with carbon spring wire end to end. Treated (?) for flame resistance, and each coil has a wear-resistant strip on the outside, where the spring makes contact on the inside. A fine bit of attention to detail.. Heat range = -22F to 212F. Has three attached D rings including three load hooks for mounting. The D rings are riveted to the PVC hose, so not sure how long they will remain stable. Probably a very long time if mounted and left undisturbed. It's obviously high-quality, so even tho the $53 price seems high, it's worth it just in endurance alone. Meant for providing ventilation and/or exhaust vents, easy to add a fan to the end with the adjustable strap. Well put together, should really hold up to long term use. Obviously sold for use in a professional shop setting, with high performance exhaust fans. The 25 foot length is giving great exhaust clearance for our garage. Also is venting the garage when needed of hot, stale, air, and keeping it cooler inside, which is great for the two deep freezers we have out there! With this vent attached to even a box fan, it's staying 15+ degrees cooler than it was. Much less stress on those freezers. I am really appreciating it. FIVE STARS
