MR and MR D Series Installation Guide

Modifying a Mud Ring

Each mud ring size can be modified to make the mud ring one gang-size larger or smaller (figure 3). You can resize the mud ring by either adding a top and bottom segment, removing a top and bottom segment (2- through 7-gang size only), or replacing one size top and bottom segment with another.

NThe 1-gang mud ring cannot be made smaller.

Modify the mud ring as follows:

1. As necessary, remove the segment assembly screws that hold the segments together, and add, remove, or replace a top segment and a bottom segment.

NFor example, to modify an MR 300 to be a 4-gang mud ring, add one small segment on the top and bottom. To modify the same MR 300/MR 300D to be a 2-gang mud ring, replace the large segments on the top and bottom with small segments.

2. Replace and install new segment assembly screws as necessary.
