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)

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

The panels were a pain to begin with and did not sit in the frame well. I rigged up some insulation to offset this annoyance only to find out that the hose attachment collides with our windowsill. Avoid this product if you have vertical sliding windows. Hoping I’ll be able to get a refund.

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

Looks grey in photo on Amazon but it’s white

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

This insert was exactly what I needed.

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