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

As described, feels sturdy also

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

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

Useful

GOod but not for comercial

Good quality!

This is a high quality air tight flexible duct with some pretty long range for its compact form factor. 33 feet compacts down to only a few inches thick. I have a lot of different blower fans, sometimes for bringing clean air in for positive pressure most often than not as an exhaust for dust or particles. Normally I use the standard clear HDPE style flex bag tubing. This has two major issues 1) It is slippery and pressure makes it want to pull off the fan when it is strapped to it. 2) It is horrible with corners. It wants to kink around any sort of bend cutting off the flow. I have worked around this using PVC or HVAC elbows slid over it, but it is a pain and takes some time to get right. More than a few corners and its just a massive hassle to get them all in the exact right places. Half the time when you start it up then it moves and kinks elsewhere. You also can't easily attach it to a ceiling or strap it somewhere as it collapses when not inflated and has no attachment points otherwise. This fixes all those things. Not only is it far less prone to be pushed around compared to the the HDPE style tubes but it also includes a great cinching cord on one end that makes it easy to clamp it down over most fan ends I would guess. The built in steel wire ensures it doesn't kink when it is going around a corner or collapse in on itself. It includes multiple metal anchor loops that could be used to hang it from a ceiling or similar. As with any sort of the spiral metal ducting you want to minimize turbulence for best performance. It is best to have it taught and if you don't need the entire length to bunch it at one end rather than over the entire thing. This is large ducting though so you may not care about loss. Some discrepancy in temperature range. One photo said it works to 120C and the description says 100C. Note as well it is not symmetrical, only one end has the easy cinching cord and setup. If for some reason you need to attach to both the other would be more difficult. For me I can't remember the last time that was the case. The only thing that might be more helpful would be a few more d-rings for help with routing or less drupe when hanging. Overall very affordable for high quality ducting.

It comes as ordered, the size and width, great product use it with the exhaust fan daily
