AdaptAIR® Roof Vent Adapter (1-Pack) for 20' Shipping Container/Conex Setup - Fits 12-Inch Turbines - Pair with 1-Pack Turbine, Sold Separately

After struggling with a stock vent from Home Depot and trying to hammer the sheet metal to conform to the grooves of my 10x20 container, I found this sweet premolded vent adapter! Not only did it come with everything I needed (Caulk, screws, etc), it fit perfect and was on in like twenty mins! I'll be buying more when I need another container vent. Thanks!

A couple of suggestions based on my initial installs. I watched videos and read posts about these before ordering, my OCD will save you a lot of headaches/heartaches. Toss the screws, driver and drill bit and buy some quality replacements, slightly longer stainless screws are advised. I have installed 3 of these and those included items suck. Take your adapter to the hardware store and test fit your whirlybird turbines to verify they fit snug, they are not all created equally. When you cut the vent hole, cut it round to match the inside diameter of the vent adapter using a jigsaw, it's stronger, cleaner, no chance of sparks/flame and gives you more room to seal against any leaks. Also, do all this when it's cool outside to give you time to work the sealant and you won't suffer from the heat reflected off the top of your container. Predrill a couple of holes and partially install a couple of the new screws, finish drilling the remaining holes, then remove the 2 temporary screws and deburr all the the holes inside and out, deburr the round vent hole, blow or sweep any "shavings" away and paint the drilled holes and the edges of the cut hole with a quality primer/paint good for bare metal. Allow the paint to dry and then use a good metal sealant to seal your adapter, tighten the screws incrementally to push any excess sealant to the edges, put a small bead of sealant under the heads of the screws and finish tightening them until they are good and snug. When installing your whirlybird turbine, use some of the better screws you purchased to secure your turbine to the adapter. They also work great with additional cross flow vents, you can feel the air flow and you can see the benefit of the vents if you monitor the temperatures and humidity before and after. I have 3 Sensor Push HTP.xw sensors in the container and know the combination works to keep the interior temperature acclimated to the exterior temperature. Thank me later

I installed these on top of a 9h x 8w x 45 feet long shipping container. I put 2 on top evenly apart. It helps keep the inside cool in summer and warmer in winter. I store my belongings in the container and I have no mold, no sweating of my items, no moisture period. I also put in 8 small air vents on the sides and 2 large vent on the doors for better circulation. It has worked perfectly, my items are safe from destruction. I greatly recommend them to anybody who is storing their important items in a cargo shipping container. I think I did this about a year ago.

They were exactly what I wanted!

Fits pretty well, good enough to seal around it. Pretty expensive for what it is..

I can say they they came in on time. I ordered them as a gift for a friend and I do know know anything else about them.

Wish I had when venting my first shipping container. Used for the last 2 & much easier & cleaner to install

Scammer tried to buy it; don’t know why; never needed it! But it looked great when I sent it back!
