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)

Compatible with many units and very strong material that will last.

Its way too big for my Honeywell AC unit.

> Adjustable length range: 17 inches to 65 inches this is not true it works either for 17 or for 27-65, but not for anything between 17 and 27

I bought a used portable AC unit and the seller lost this very important piece. Found it on Amazon used for a reasonable price. Aside from the color difference since we have another unit with the OEM window panel vent, it works perfectly. Good quality. Even though it was sold as used, looked brand new to me.

The plastic is very thin. So if you have to extend to the maximum length very flimsy. If the product was just made thicker and more durable it would be a great product. Easy to install.

Serves its function. But built flimsy. Not enough foam included to seal around the uneven edges of the plate.

Like many others, this extension kit is far better than what came with the DeLonghi air conditioner unit. As a determined 65 yo, I was able to install myself. It would be easier with 2 people but doable alone. Instructions could be a lot better, I watched a You Tube video to make sense of it before starting. No tools needed other than scissors to cut sealing material. Plus, plenty of sealing material. It is very sturdy, appears to be durable but this is just my first season. I would highly recommend.

I have an LG portable air conditioner fit perfect and does the job

It was a major bummer when I realized that the stock window kit that came with DeLonghi Pinguino PAC EM370 was too short to fit in my 46 tall window. After combing through some reviews and seeing positive comments about this particular window kit working well with DeLonghi ACs, I decided to give it a go. I can confirm that this kit indeed works well with PAC EM370. All I needed to do was take the stock hose attachment with the one included in this kit and everything worked like a charm. Installation was easy and includee sealing tape was very handy in ensuring a tight seal. While not premium quality, all the parts were sturdy and well fitting. Happy with the purchase and will recommend!

It works very well and does exactly what it needs to
