Portable AC Window Vent Kit, Adjustable Vertical/Horizontal Sliding Window Kit Plate for AC Unit, Seamless Portable AC Window Seal With 5.9 Inch Diameter, 59 Inch Length Exhaust Hose

So easy to assemble and fit to my sliding window. It fit perfectly to my new portable air conditioner. I highly recommend this product.

Fits great

Overall, it's pretty good. Other reviews are correct, but there is a caveat: if the panel length you need is longer than the ~17in of the first panel (the one with the hold for the vent), but only by a little bit, then the second panel doesn't have room to clear the vent hole. None of the panels are shorter, and you can't insert the vent tabs with the vent blocked like that. I ended up taking a mitre and saw and cutting a panel down to size. So now it works, but be aware if you need it to be less than (and I am guessing here, I haven't measured it) around 22-24 inches then this might be an issue.

it’s good if u don’t have a cat trying to escape they can dig there claws in the sides and pull it open

The price is great for all the pieces that come with it I had to tape the 2 connector together so they can stay with out falling out. I love that it comes with extra window pieces just in case you want to put it the long way up and down I am using it the long way side to side
