Universal Window Seal Kit for Portable Air Conditioner of Exhaust Hose 5.1 Inch Diameter with Coupler Adjustable AC Vent Kit PVC Seal for Sliding Window

Does what its supposed to do.

Not sturdy when put together and installed. There’s no way to strengthen it. Waste of money if you’re using it in sliding glass door.

Pretty sturdy and easy to set up. I needed a wider extension because my window was too wide for the factory portable ac unit window attachment. It was perfect in size and more if needed. The foam seal roll that came with it is also a plus. Great product does the job.

If your window is somewhere roughly between 17 inch and 21 inch you will need to cut the back plate down to size as the circular duct attachment protrudes out the back. Pretty expensive for what it is but then it appears they all are.

Easy to install. Works just like described.

Big gaps on the slider pieces even after applying foam roll. Probably going to have to do something like tape some bubble wrap on, which is unfortunate.

I havent used yet because I have to go and buy thicker weather seal. Kinda a bummer but will see after I get some. Also the roll they send with it definitely isnt enough for both sides

Product came as described and has worked as it is intended to do.
