Installing an Extron MR Series mud ring
Depending on the MLC model or MLM faceplate you use (other than lectern mount
or EC/EU models), you can install the MLC 104 Plus Series controller using the
following Extron mounting brackets (mud rings):
• 2-gang mud ring, black or white (part #70-519-22 or -23)
• 4-gang mud ring, black or white (part #70-519-42 or -43)
• 6-gang mud ring, black or white (part #70-519-62 or -63)
Determining the installation location
The UL-listed MR series mud rings do not need to be fastened to wall studs, so
they can placed almost anywhere on a wall or other mounting surface. When you
are deciding where to install the device and mud ring, consider the placement of
the cable(s) and access. You may need to install the cables before you install the
bracket.
W The MR series mud rings are UL‑listed for low‑voltage applications only.
N The mud rings fit securely in hollow wall thicknesses ranging from
1/4” (0.63 cm) to 1” (2.5 cm).
Preparing the site and installing the mud ring using the doglegs
1. See the to-scale dimension drawing included with the mud ring to determine
the cut-out dimensions for your mud ring. If desired, make a photocopy of
the template. Cut out the material that corresponds to your mud ring.
N The solid lines on the template define the cut‑out area, not the dashed line. For
example, for a 2‑gang mud ring, the cut‑out width is 3.95”, not 4.60”.
2. Use a soft pencil to mark the guidelines for the hole to be cut in the
installation surface. If you are going to screw the mud ring to the surface,
rather than using the doglegs, mark the four screw holes at the corners.
3. Carefully cut away the mounting surface material inside the guidelines.
4. Test the fit by inserting the mud ring into the hole in the wall. The doglegs on
the mud rings should fit easily into the hole and the flat portion should rest
flush against the wall. There should not be any noticeable play or movement
of the mud ring in the opening. See the notes in the figure below.

NOTE You do not need to disassemble
the dogleg from the dogleg screw.
Rotate the dogleg out of the way to
insert the mud ring into the wall.
NOTE For solid surfaces, such as a wooden
podium, you can omit the doglegs and
screw the mud ring directly to the surface
through the four surface mounting holes.
