How does that actually attach and seal around a lift up style window? I have a portable a/c unit with one that slides to the desired size but it’s flimsy and junk I want to port my a/c and engraver out the same window. Great ideas here Love the vent covers as I am getting critters come in
The piece of plexiglass sits into the channel of the window and the weight of the window closing on it holds it in place. You could put some weather stripping around the perimeter to seal it up better.
Watched your video the other day, then I watched this one today, and immediately thought of this application for you. Don't know if its something you might want to incorporate but worth the look. Could be another option for your product line. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xc-6xVB9H4I.html
