replaced today what we removed was hollow bulb (and it was falling apart) never thought about replacing it but this seemed to work even better. Im assuming its pretty mush the same but gives better seal on my 1987 double hung vinyl window

Thanks for posting! It's good to know that the foam weatherseal worked just as well as the hollow bulb.
