Crestron MMK-4L & WMKM-4L Mud Mount Kits
Mud Mount Kits: MMK-4L &
WMKM-4L
Description
Mud Mount Kits are the preferred mounting option for the Crestron Isys®
TPS-4L and TPMC-4L wall mounted touchpanels when cutouts made in the drywall
for touchpanel installation are too large. These kits provide support for additional
plastering that can be applied to hide large irregularities in the touchpanel cutout.
NOTE: If mounting into another material (other than drywall – for example, wood
lectern, concrete, or rock) use the cutout template, available in the post-construction
kit WMKM-4L. For concrete and rock mounting material, allow for proper
ventilation before mounting the touchpanel.
There are two Mud Mount Kits. The MMK-4L is a pre-construction accessory.
Pre-construction refers to framed walls prior to hanging drywall. This accessory
must be used with either the Pre-Construction Mount Kit (PMK-4L) or Back Box Kit
(BB-4L).
The WMKM-4L is a post-construction kit. Post-construction refers to framed walls
with drywall hung. This accessory is designed with a mounting plate so that it can be
placed anywhere on a wall without the support of a stud.
NOTE: If necessary, consult the latest revision of the TPS-4L Operations Guide
(Doc. 6449) or the TPMC-4L Operations Guide (Doc. 6450) for a complete list of
mounting options. Both documents are available from the Crestron website
(www.crestron.com/manuals).
Supplied Hardware
The MMK-4L consists of three parts. These parts produce an assembly that attaches
to the PMK-4L or BB-4L. The WMKM-4L consists of five parts–three of which
make up the MMK-4L–as well as one mounting plate and one cutout template. The
mounting plate provides the necessary support for post-construction applications.

Installation
This section provides an installation procedure for each Mud Mount Kit. The
procedure for the MMK-4L starts below and the “WMKM-4L Procedure” starts on
page 6. Be sure to review each procedure before starting.
MMK-4L Procedure
The procedure in this section provides the necessary steps for the assembly of the
MMK-4L to either the PMK-4L or BB-4L. It is assumed that the PMK-4L or BB-4L
has been secured to the stud according to the procedures in their latest Installation
Installation Guide – DOC. 6389 Mud Mount Kits: MMK-4L & WMKM-4L •3

Mud Mount Kits Crestron MMK-4L & WMKM-4L
Guides (Doc. 6388 and Doc. 6387, respectively). Also, it is assumed that drywall is
in place and a rectangular cutout for the touchpanel is made in the drywall.
Complete the steps in the order provided. The only tools or materials required and
not supplied are a drywall saw or equivalent, four standard drywall screws, #2
Phillips screwdriver, a level, and tools/material to apply drywall joint compound.
CAUTION: Allow an air gap of at least 12 inches in the wall cavity above and
below the touchpanel for heat dissipation.
NOTE: The illustrations in this procedure show the installation of the MMK-4L
with the PMK-4L. Even though the illustrations only show the PMK-4L, they are
identical for the BB-4L as well.
1. Pass an adjustment plate through the opening and align its two center
holes with the top two pins on the PMK-4L. Verify that the pins on the
adjustment plate are not between (facing) the adjustment plate and the
PMK-4L. Refer to the illustration after this step for visual guidance.

2. Slide a push-on fastener over each pin of the PMK-4L (or
BB-4L) to loosely secure the adjustment plate and the mounting plate.
Do not push the push-on fasteners all the way down onto the pins. Slide
them on enough to keep the adjustment plate and mounting plate as one
adjustment/mounting plate assembly.
3. Use the second adjustment plate and repeat steps 1 and 2 using the
lower two PMK-4L (or BB-4L) pins.
NOTE: When installing into the PMK-4L, verify that the 18 AWG bus wire
securing the cables for the touchpanel remain attached.

illustration after this step.

5. When the mud ring plate is in position, bend the top two flanges of the
plate upward and the bottom two flanges downward.
• If mounting into the PMK-4L, bend the flanges approximately
90 degrees.
• If mounting into the BB-4L, bend the flanges back as far as they
can go.
6. Use four standard drywall screws (length should not exceed drywall
thickness by more than ½ inch) to secure the mud ring plate to the rest
of the assembly. The screws pass through the clearance holes in the
PMK-4L (or BB-4L) and are secured in the extruded holes of the
adjustment plates.
7. Verify that the mud ring plate is level.
NOTE: Do not over tighten screws. Doing so may over-dimple or rip the mud ring
plate.
8. Use a #2 Phillips screwdriver and tighten the drywall screws by hand
so that they slightly dimple into the holes in the mud ring plate.
9. Apply drywall joint compound as needed to finish the cutout. Avoid
covering the four tapped mounting holes.
10. Run the necessary cables for the touchpanel and secure them behind the
drywall.
11. When dry, the touchpanel can be installed using the four tapped holes
in the PMK-4L. Refer to the latest revision of the
TPS-4L Operations Guide (Doc. 6449) or the TPMC-4L Operations
Guide (Doc. 6450) for installation instructions.

WMKM-4L Procedure
The procedure in this section provides the necessary steps for the assembly and
installation of the WMKM-4L into a wall. Review the procedure and complete the
steps in the order provided. The only tools or materials required and not supplied are
a drywall saw or equivalent, a level, four standard drywall screws, #2 Phillips
screwdriver, and tools/material to apply drywall joint compound.
CAUTION: Allow an air gap of at least 12 inches in the wall cavity above the
touchpanel for heat dissipation.
1. Insert the two pins on one adjustment plate into the top two outer holes
on the mounting plate, as shown in the following illustration.

2. Slide a push-on fastener over each pin on the adjustment plate to
loosely secure the adjustment plate and the mounting plate. Do not
push the push-on fasteners all the way down onto the pins. Slide them
on enough to keep the adjustment plate and mounting plate as one
adjustment/mounting plate assembly.
3. Use the second adjustment plate and repeat steps 1 and 2 using the
lower two pins.
4. Locate an area on the wall that is free of miscellaneous wiring and
studs.
5. Make a small hole near the middle of the designated site; verify that the
location is suitable.
NOTE: Make the cutout as level as possible. The mounting plate allows for only
minor leveling adjustments.
6. Use the drywall saw or equivalent to produce a level, rectangular cutout
in the drywall as shown on page 3.
7. Insert the symmetrical mud ring plate into the opening, as shown in the
illustration after this step.

8. Carefully pass the adjustment/mounting plate assembly through the
opening and rest the assembly against the interior surface of the
drywall. Verify that the adjustment plates are between the mounting
plate and the drywall.
9. When the adjustment/mounting plate assembly is in position, bend the
top two flanges of the mud ring upward (approximately 90 degrees) and
the bottom two flanges downward (approximately 90 degrees). Refer to
the illustration after this step.
NOTE: Adjustment/mounting plate assembly will have slight play; this is normal. It
allows for minor adjustments to the touchpanel during installation.
Bend Flanges
10. Use four standard drywall screws (of adequate length) to secure the
plate to the adjustment/mounting plate assembly. The screws pass
through the clearance holes in the plate and are secured in the extruded
holes of the adjustment plates.
11. Verify that the plate is level before tightening.

so that they slightly dimple into the holes in the mud ring plate.
13. Run the necessary cables for the touchpanel and secure them behind the
drywall.
14. Apply drywall joint compound as needed to finish the cutout. Avoid
