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)

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.

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

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

It is just perfect

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

Fast delivery. It’s adjustable to fit most windows. It was just a tiny bit to big for the hose on my air conditioner but I will just tape it tight. Couldn’t find the exact size. It will work.

easy to install

Am happy with it

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!

Item was of the most first-rate quality. Swift to send. Very tasteful packaging. First-class seller.
