400CM (157)Universal Window Seal for Portable Air Conditioner And Tumble Dryer – Works with Every Mobile Air-Conditioning, Easy to Install - Air Exchange Guards With Zip and Adhesive Fastener

After some reviews said they couldn’t make this work for crank out casement windows, I was hesitant, but thought I’d give it a try. This was so easy to install. I ordered slightly larger than the window opening and had to overlap the ends, still there was plenty of hook and loop tape. I needed to vent a portable ac unit for my parents, who have never had ac before and were concerned about damaging their windows. This was a great solution, especially because it will be easy to remove the fabric pieces but the hook and loop tape can stay all year. Can’t speak to durability since we just put it up. So far, Great product.

I bought this as a way to vent a laser cutter exhaust outside. My casement windows open outward, so had to think a bit when installing. Initially I had the 3 vent a few inches from the bottom of the window with the zippers holding it up. It was below freezing outside. This caused the double sided tape to pull off the frame. I added more tape and moved the vent pipe lower so less pull. Works great now. I was able to install in such a manner that I can even put the screen back in the window and use if I unzip the seal.

For several years I struggled with the problem of effectively sealing my double French window in order to vent my portable AC. Best I could do was cut to fit and wrestle into place a gi-normous piece of cardboard cut from a shipping box to cover the full window frame. Blocked the light, less than airtight, and really, really Ugly. This is a simple, low tech solution. The double-access zipper tags (intended for 2-hose ACs), allow for a hand to reach out to adjust and reposition the (single) vent hoses snout when necessary while maintaining a grip on the hose. While not exactly an aesthetic ideal, the strip of white fabric is far more discreet than cardboard, only one side of the window is open, just enough to accommodate the width of the hose. The curtains remain in place, I have daylight, and the street view is barely noticeable. And, yes(!), the AC cools efficiently. Because it had to line the top of the one open side of the window as well as the vertical gap between the two, it took nearly the whole length of the fabric, with only inches to spare. I am in a drought area, so had only one wind/rain event in several months, but it held up to it. Once the weather cooled and the AC stored, I had to also remove the hook strip of the velcro to be able to close the window normally. It lost most of its sticky, so may have to buy/cut some new next time.

easy part was the tape stuck around the patio door frame then the difficulty came with placing the Velcro evenly on it I double up extra fabric in left corner and bottom wrong move it was to tight then I put the hose through cut it on all my efforts came down had to retape so barely press the Velcro down on the tape next I put the hose through the zipper which was extremely hard because it doesnt not close around and the zip ties good luck fortunately after some hours eureka it was done not perfect but doable

I was pleased to find this easy solution when I was gifted a used portable A/C unit without any sort of window fit kit, especially for my outward opening windows. Although the directions were not quite as clear for outward opening windows, they did describe the adjustments that would need to be made. After watching the instructional video for inward opening windows, it was not difficult to understand the adjustments for outward. I also agree with others that the white plastic is still more pleasing to the eye than a big piece of wood or cardboard stuck in the window. It seals up nicely so no trouble with letting in bugs, rain or debris. Ive had it installed for about 3 weeks and it has worked very well.

It took us a few minutes to figure out the instructions but after watching a quick video, we were able to set this up quickly. It works as advertised and fit well on our outward opening crank window. It has also stood up to some wind and rain storms. Very happy with this purchase. It would be very easy to move to a different window if we wanted to move our portable A/C unit elsewhere in the house.

easy to install it.

Allows me to use an air conditioner in an unusual window and still close the window when not in use.

Not only is this product great, but their customer service is fantastic! The install was easy and the company reached out to me before and after delivery to make sure that everything is good. Finding customer service like this is rare to say the least. They are fantastic!!!

The air conditioning in my upstairs bedroom has not worked for years. Unfortunately there is no window in the room only French doors so I could not get a window air-conditioner. I am not crafty or handy in any way so rigging something with the French doors was out and I did not want to spend thousands on a ductless air-conditioner. I stumbled on this product and thought I should give this a try. It was easy enough to install. I had to get some extra velcro bc I put it in the wrong place on the door frame but once I figured it out it was simple and only took like 30 minutes to get the whole think up. The hose fit in the zipper hole and I used the zip ties to keep it in place and used some ductape to really seal it all the way. All in all this product was a cheap way to make an otherwise very uncomfortable room livable. I would definitely recommend getting this product. I also watched the YouTube videos in the question section and they were very helpful.
