Modify an MR Series mud ring as follows:
1. If necessary, remove the mounted device(s) from the mud ring.
2. If necessary, remove the mud ring from the installation surface.
3. As necessary, remove the segment assembly screws that hold the segments
together and add, remove, or replace a top segment and a bottom segment.
The following table shows the modifications required to enlarge and shrink

As an example, to modify an MR 300 to be a 4-gang mud ring, you add one
small segment on the top and on the bottom. To modify the same MR 300 to
be a 2-gang mud ring, you replace the large segments on the top and bottom
with small segments.
4 Replace and install new segment assembly screws as necessary.
5. If necessary, enlarge the opening in the mounting surface.
6. If necessary, reinstall the mud ring in the mounting suface.
7. If necessary, reinstall the mounted device(s) in the mud ring.
