Hi Gordon, Glad to hear you are happy with the product and thanks for the positive review. I'm going to look into the track situation for you. What you say makes sense, but my understanding is that separators were removed a few years back mostly for cost but also environmental reasons. The tracks should be packed 'base to back' though, so that if scratching or rubbing did occur, then it would be on the underside of the bottom track and the top side of the top track, both of which are hidden from view. Let me know if yours was otherwise. Sincerely, Mark @ SWW
