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)

Fit just as needed in my window that is slightly larger than average, which is exactly what I needed. I love the easy ability to expand to the required dimensions. It’s been doing great for about 3 months now. Got some weather strip at Lowe’s to go with and it’s worked like a charm.

Worked on refectory for my situation

Served us well

For real. This is the solution.

Hose connection is a non-standard size, a little disappointed

I bought this to replacement for my DeLonghi free standing air conditioner and it works well.

its ok. just dont move the hose or look at it too much and it wont falll off. its mainly how the hose attachemt hooks to the window spacer. mine is always falling apart.

This insert was exactly what I needed.

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

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.
