The may be a problem with the term “vertical”. Others assume this means the pipe is vertical and the face of the face hub is therefore horizontal. If that is the case then the previous answers about cutting off the hub will work. But then making a lead joint is also a simple process. But since the majority of lead connections are into a tee in the main stack, which makes the pipe horizontal and the hub face vertical, cutting off the hub will compound your problem immensely.
