Gruntbear Universal Window Seal for Portable Air Conditioner, Portable AC Window Seal Kit, Hot Air Stop Air Exchange Guards with Zip and Adhesive Fastener Works with Tumble Dryer (400cm/157inch)

I purchased this for my old casement window and did the trick. Thanks

This is supposed to be for a window that cranks IN. Mine cranks OUT (I have never seen windows crank in). I made it work and it works GREAT!!! You just have to remember to close the window before it rains, so the rain doesnt pool on the top.

I was so relieved to find this so I could use a portable AC with my stupid crank windows. This thing is really simple to use and gets the job done. Only complaint is that the Velcro isn’t super sticky: I had to reinforce it with duct tape in several places. Not the end of the world though and still highly recommend if you need to make a portable Ac work in stupid windows

Not as described. Doesn’t show in pictures that it tapers which didn’t work for my larger opening even though under the size they mention. Velcro tape already peeling off a very clean flat surface. Junk really.

lf you have a casement window that pushes out when you open it, then it’s basically the opposite of what they’re telling you. I think the picture I have attached is how they want you to seal the window with the narrow pointy side on the bottom of window and top, and the larger, wider opening with zipper in the middle for the hose but I’m not sure. I did it another way and it worked better but I had fabric left over.

I have some older windows in my house that I wanted to be able to put a air conditioner vent out this was very easy to install very durable and works as it should

This is just what I needed for my single hose portable A/C (though I see it can accommodate two hoses if needed. It is a bit odd to contemplate and visualize at first (I thought), and the illustration with the directions I found bizarre, but the product itself is a great quality and very logical in how it attaches to my window. As the circumference did not quite reach all the way around my window (I did not want a larger size with a lot of gathering to contend with), so I just purchased white painters tape to complete the last 6 near the window hinge area and that seems to work great. Do pay attention and measure your windows.

Product does what it says , BUT the adhesive strips that hold it together are horrible and keep falling apart.

Does what it’s supposed to do, no issues at all

If your city is hot, then these will not only melt off your window but make a sticky disaster everywhere. The application is easy but still is tricky to position everything without openings. Not great overall.
