Portable Air conditioner Window Kit, Adjustable Vertical/Horizontal Sliding Window Kit Plate for AC Unit, AC Window Vent Kit, AC Window Seal Suitable for 5.9” AC Exhaust Hose (AC Window Kit-5.9)

For some reason this year that part came up missing, this product worked

I have an old Delonghi portable AC unit and for the life of me couldnt find my window kit. I purchased this right at the beginning of summer and with it being adjustable it fit my window perfectly. Comes with everything you need. The adjustment screws held very well and lasted all summer. This time I made sure to put it away safely so I can use it again next summer.

This insert was exactly what I needed.

Easy to install, lower profile than the original window kit.

Our portable AC unit came with window connections that are probably great for newer houses, but our >100 year old house has narrow windows. This kit let us adapt the AC to our narrow double hung windows. Isnt a perfect fit, but it is soooo close that well take it! Easy to cut the pieces to fit. And the sealing tape that came with it is perfect to fill the small gaps. We are so pleased. I would definitely recommend for those with narrow windows. Only bad thing is all the extra plastic parts we wont use and will be adding to the plastic waste of the world. Heavy sigh.

Fits perfectly!

It didnt insulate well enough, I had to tape it to the window.

Fits both sliding window, just wish it had a drain hole for humidity hose hook up

The difficulty I encountered installing this was: a) wouldve been easier with 2nd set of hands b) basic instructions wouldve helped c) I was adapting it to a different feed connector & it took me far to long to realize I was approaching it wrong. Some or none of these problems could happen to you. All that being said, in the end it fit perfectly on my oversized vertical windows & Im very happy to have found it!

It was designed to fit up to 62 inches I believe. It did that, but left side gaps between the parts that slid together. They include weather stripping which is good, but this being a seasonal installation, I did not want to put foam strips in the window frame. A wider frame and weather stripping on it would be much better. I wanted to use the hose and connectors parts that came with the AC unit rather than taking the hose apart to use the parts from the kit. I just designed a 3d printed oval ring that let me use the kits oval and the B&D hose adapter. That made it work perfectly.
