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

works well wish came in smaller size for the vent hole, a 4inch hole would have been preferred but it was difficult finding one that had a 4 inch hole.

Its not bad construction, but there are issues unsolved with this solution. First, the window is open meaning hot/cold outside air will hit the sliding window and be forced up behind the fixed window right into the room. Second, the channels do not block hot/cold air, either. The outside air hits the seal kit and passes unimpeded into the room. They could have solved that with a notch that fit into the channel ahead of the metal plate. Last, the sides of the kit are thin material making it impossible to secure the sealing foam and block air from passing around the kit. 3 flaws there. And, why did they send 5 sets of plate/screws?? The installation 5x7 is totally insufficient.

The concepts is simple and this product does in fact hold the exhaust vent in the sliding door… BUT when it comes with a broken hose connectors it renders this item useless!!!

EZ as pie to install .

Fit in window and very easy install.

The hole was a bit small for our AC tube. I used a knife to enlarge it, which is not too hard. I think it worth the price than the other $45+ similar products in Amazon. We didnt use the tape that comes with the product. I wish theres an item without the tape but with a cheaper price.

4 extensions in heavy-duty plastic, not thin. Connectors are easy to use and better than most that come with a portable a/c. Quality product.

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

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

Perfect
