Went to my local dealer today (Dillons RV) to get a piece of the foam seal that is used all around the two halfs of the Hi-Lo.. The piece that is on my screen door has cracked on the end , exposing the foam inside. The Dealer says just this month Hi-LO has changed the type of seal they use , and gone to a all rubber style. I think this is good news, out here in the west with the high heat the plastic covering on the foam type seal can get hard and crack. Here is a picture of the old piece off my Hi-Lo and a piece of the new type seal. I like it.
