HI, I have the same problem with the seal tearing at the roller. If the seal was narrower to start with, it would not get caught on to the slide roller when you close the slide. Now mine is shot and would like to know where I can get a new rubber seal other than the dealer because I have a hard time getting parts from him.
Fix!!!!!!
I cut out the extra rubber like (bsummit) did and that will take care of the pinching on the roller except for 2 rollers where the rubber had been cut off, now I have a couple hole in the rubber that don't seal with the bottom of the slide.
When it is close it won't matter but open some bugs could crawl in!!!!!!!!!
