The difference is in the mounting position. XLCH mounts from the top, XLH mounts from the bottom. This translates to the trim ring mounting 180 degrees different on each model. The hole for the tab on the trim ring is facing the same direction as the mounting stud for the XLCH, and 180 degrees away from the mounting stud on the XLH. Same with the drain hold and attachment point for the screw that holds the trim ring in place.
