I am looking for a casement window air conditioner. I have Andersen crank out windows. 25" w x 43" high. I haven't been able to find a casement air conditioner to fit the width. They all seem to be about 15" wide and don't seem to have the adjustable sides that the standard window a/c's have. I know I can get a kit to adjust the height, but how do I make it fit the width?
Thanks
