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

We returned the item, as it was not what we needed.

The wrong one was shipped but I used it anyway. It is a very high quality plastic.

Where do I start? 1) The assembly needs to be 1 to 2 wider. Not enough clearance between the connector and wall to get a clamp on. Work around put the adapter on exhaust duct and tape it. 2) Top and bottom is not wide enough to put a seal. so you have gaps at top and bottom. 3) Top and bottom of window frames have a ridge that the window slides on. The vent assembly has no cut out for these. 4) The assembly is very flimsy. Over all if this sold for $10-$15 it would be a bargain. But for what they are selling it for, not such a good deal and Id seriously consider going to Home Depot or Lowes and get some plywood and make my own.

I bought a very expensive Frigidaire portable AC and it came with a flimsy cheap window kit. This is as sturdy as metal....maybe it is....and took no tools or tape to work correctly. This is what should have been included in the $550 the portable AC cost. And BTW, 5.9 is the same as 6 when it comes to the hoses on these portable units. So Frigidaire says its 6, they really mean 5.9.

but the plastic is thin

Doesnt seal at all or hold in any of the cold air your bringing in from fan I dont recommend it unless you are just wanting to keep the bugs outside by having window or slider mostly shut

The hole for the hose to vent through is less than an inch from where the screw plate is supposed to go to attach one of the sliding plates, so the vent has to be at the bottom or at the top of the door, as there is no way to attach both both a plate and the vent. It would be better to put the vent coupler in the center of the panel so that the height can be adjusted using the sliding plates. After struggling with it, I used the black foam strip provided to brace the plates against the door frame, top and bottom; otherwise, it flops around. The foam strip is too firm to fill to the gap between the plates and the door. Did I mention that the foam provided is BLACK? The kit panels are a very light grey and the frame for my sliding door is silver--why would I want an ugly black strip between the two? Fortunately I hase some more forgiving grey foam weather stripping to use. I also used silicone weather stripping tape, which provided a satisfactory seal. Hooray for 3M! The design overlooks the fact that the sliding door lock is right in the middle of where the plates are supposed to go, so I had to work around that as well. Just poorly designed.

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.
