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)

I used a little hand saw to cut to fit my little windows and it was super easy

If you need some extra space these might give you a bit more than what came with the air unit but the fit around the sides is not great and the pins to keep it locked are not great

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

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.

Good kit at fair price. Easy to install in various sized windows

it was easy to install with the given instructions and is very sturdy

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.

I highly recommend this
