Old post I know. So is this elusive rubber grommet the only thing keeping the little stainless trim ring from falling out of it's hole? I have just assembled all this from parts and that piece keeps moving around...I can't see a way to secure it. It doesn't have the rubber grommet so am I right in assuming that just jambs the whole thing tight?
Thanks
