Container Modification World® - BigAir™ Louvered Gable Vent - Product Line - for Preventing Condensation and Excessive Heat in New and Used Sea Cans (BigAir30™-2PK-with-Screen)

Awesome well built easy to install vents for shipping containers. Massive improvement in air flow.

A bit pricey, but worth the money, helps take the intense heat out of my conex box, very pleased

These are great little vents and fairly easy to install. The hardware was great and easy enough. I went the extra step and sealed the robots and edges once installed to ensure an even better seal. I put one at the top on either end, opposite sides of my container hoping for some airflow, no luck unfortunately.I think though they might be a little too small for my 20’ container as it still gets a lot of moisture and still isn’t venting well enough even with the container in a fairly shaded area with minimal moisture. Might have to go to a roof vent or something for mine.

These are a little pricey, but work great. We build a few of our own, then found these. They same so much time for us and easy to install. They are great quality. Happy with our purchase.

Fast shipping, well package, clear instructions. You can also look at video website/YouTube. Measure twice and cut once. Used friends Ryobi 18v cordless angle grinder done ok with this steel. Measure the vent it's slightly bigger than template that comes with instructions. Had no problems with rivots. Did break a cheap bit so get quality bit. Mine didn't come with bug screen. Other than that just the price is major con for me.

Installed both of these down low towards the back of the 40' container. With the doors open, I can absolutely tell a huge difference in ventilation. Soon I will install a rooftop solar fan and not need to open the doors. The construction of these vents is top notch and with a little caulk to seal everything up, they should be good for a very long time. If you are going to use the pop rivets, which is recommended, get yourself a pop rivet tool that chucks in a drill. I have a high quality handheld tool, good grip strength, and it was very difficult. So get a good pop rivet tool.

the price was way to much paid for expedited shipping and it took forever to deliver, IMHO it should be resized to fit the container curves you have to be super precise where you cut to make sure you have enough space to drill in the screws go to far left or right and screws would fall in cut area

Well worth the effort it takes to install these, no more rain IN the container from moisture!

Used these for my container. Quality built and everything needed for installation comes with them. A little caulking of my own and job done. Thank you

My sea container on the farm had horrible 'container rain' and so ruined some equipment. I installed this in about an hour and so far zero condensation or worry. Note: use a reciprocating saw instead of a grinder, so much easier and faster.

Fits good and works well but find they are too expensive for what you get.

I have several seacans so ran an experiment - installed a pair of spinning whirlybird type roof vents on one and these on another (one on either side, staggered top and bottom as recommended). I then installed three cheap digital humidity/temp meters inside each can and a couple outside (thanks, Amazon). Although they’re not quite as exciting to watch as the whirlybirds, these vents did a way better job of provide consistent humidity and temps through the can, and the humidity levels inside were more closely aligned with external humidity levels (hopefully no more seacan rain). These vents most definitely work as promised.

Good quality. I have bought more.
