AdaptAIR Roof Turbine Vent (1 Pack) 12 inch Roof Vent Adapter - Designed for Conex Container, Shipping Container House, Fits Whirlybird Roof Vent and Solar Roof Vent Fan by Container Creations

Really great! Fit very well. I need a couple more. I wish they weren't quite so expensive.

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

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

Very high quality turbine. Whisper quiet !!

They were exactly what I wanted!

Very heavy duty, comes with mounting screws, drill bits, etc. DOES NOT FIT SIDE WALL, REAR or DOOR PANEL RIBS. Only fits snugly on the roof of standard shipping container. Very pleased with purchase.

Built well. Easy install. Didn’t come with any of the supposed included small items. Screws, scuff pad. For the amount of money it should include adhesive/silicone, alcohol, and to be honest the turbine too. Count on spending another 50 bucks on that.

This product is good .. great fit .. excellent ventilation…. But should be sold with wind turbine…

Worked as expected.
