You mention escape window so I will share this. I bought a 14 yr old FW that still had a heavy zip tie securing the escape window arm. It was used during shipping and never removed by the dealer. The previous owner never noticed it I guess. Scared me when I spotted it. The previous owners answer to everything I mentioned was " We never had a problem with it". No I suppose you wouldn't until late one night when you cant see and are choking on smoke and trying to break a 1/4 wide zip tie. I know the handles can pop out of the holder notch so I just use a twist tie like those used on a bread bag. It's enough to keep it seated but very easy to break. Instructed DW how to use it also.
