There are several more secure ways of installing the ceiling mount but I would need to know more about the area it is being placed (size, location, height, too many factors without actually seeing it). I recently built a half wall in my garage to enclose "My" training area. I then used some 4x4's to build a frame over the training area and used galvanized pipe to create bag hangers. I will be drilling holes into the pipe to lock the bags in position with hitch pins and when it's time to roll or spar, remove the hitch pins, and slide the bags out of the way.
Sorry for the extended reply to a simple question. I just don't like hanging bags from the ceiling. I've damaged too many houses that way.
