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

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.

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.

The insert that came with the a/c was too short. This gave me the extra length I needed to fit the tall windows.

Packaging looks like this is a full kit with a hose. It is not. Im not sure why someone would want a window kit minus a hose, but now I have to shop for one of those as well, hoping it will fit this kit, because it is apparently completely impossible to find a full kit that is 5.1 and matches my unit. (The old hose and hose attachment have melted from so many summers of use).

Easier than the original component.

When I bought a portable air conditioner without a window kit, I looked for a semi-permanent way to exhaust it through the window. After a few days using some pieces of cardboard and PVC from another kit -- with lots of backflow of hot air from outside -- I received the SIKADEER Universal Window Seal Kit for Portable Air Conditioner of Exhaust Hose 5.9 Inch Diameter with Coupler. This is a well-designed kit in my view, given that the panels slide nicely together and come with a slider and bolt to keep them firmly attached. I was able to use a jigsaw to cut round edges to fit in my campers window, and the provided coupler fit my existing exhaust hose. Very pleased with everything except the foam tape included. It was dried out so that the paper strip wouldnt come off the adhesive, I was able to jam it between the panels and the windows metal trim, so that it fit by pressure and not adhesive. This was not an issue for me but it might be for other buyers, and Id suggest the manufacturer improve the quality control on the foam tape.

Perfect

Use the window seal it comes with for the slider gap and just order thicker weather seal to go over border of window kit.
