Mantle must not extend from mounting surface
more than 19 inches (22 inches for non-recessed
installations). MantelMount can not extend past a mantel
larger than 19 inches. Larger mantels will also reduce the
amount of side-to-side swivel.
The space above the mantle must be taller than the TV. The required space
depends on how far out the mantle extends. Refer to chart below and add this
additional height to the TV height to determine if space is tall enough.
Wall must be WOOD STUD FRAME only. There must be at
least 2 studs available for mounting. Wall covering must
not exceed 5/8 inch thick.
For other types of walls or other types of installations
please visit the FAQ section at www.MantelMount.com.
TELEVISION REQUIREMENTS:
1. Weight must be below 125 pounds (56 Kg).
2. Screen size larger than 50 diagonal inches.
3. Mounting screw holes are VESA compliant.

Note: This is not an installation step, only a verification.
Do not use these dimensions during installation.
Please verify that your installation meets all of these CRITICAL requirements:

Use a Vertical Brace {27} to determine if your television
is a flat back or an irregular back. An irregular back will
require spacers and longer screws to fill any spaces
between the Vertical Brace and the TV.
The Braces must be parallel to your television screen.
Choose the correct screw diameter and length for the TV.
Hand-thread screw combination into the TV to ensure
there is adequate thread engagement without hitting the
bottom of threaded insert. Use only minimum amount of
spacers (if required).

IMPORTANT INFORMATION: The Vertical Braces {27} are
a fixed distance higher than the bottom of the Lift Housing
Frame {30}. This relationship can be used to calculate
most mounting situations such as centering the TV in an
alcove or mounting the TV at a specific height on the wall.
If you measure the distance from the
bottom of your TV (or Sound Bar) to the
bottom of the Vertical Braces {27} (see:
Page 5) you will automatically know the
distance from the bottom of your TV to the
bottom of the Lift Housing {30}.
You can use this information to install the
Lift Housing on the wall in order to locate
your TV to any specific height you desire.
Example: If the Vertical Braces are
attached 10 inches from the bottom of the
TV, then the bottom of the cutout opening
should be 4 inches higher than where you
want the bottom edge of the TV on the
wall (10” - 6” = 4”).
If you are installing above a mantel, then
your installation must still have the
additional clearance for downward motion
stated in the chart in Step 9
5152
5354

The Vertical Braces {27} are always mounted higher than
the bottom of the TV. However, the Brace Extenders {28}
will be mounted one of two ways:
Without a Sound Bar, if needed - The Brace Extenders
are installed slightly above the bottom of the TV. Use the
Extenders for holes that are low on the TV.
With a Sound Bar - The Brace Extenders are installed
below the TV with enough room to install the Sound Bar
onto the Horizontal Brace {29}.
Attach the Vertical Braces {27} to the TV so the bottoms of
the Vertical Braces are at least seven inches higher than the
bottom of the TV (so that the TV covers the Recess Frame).
NOTE: If all the screws for the back of the TV can fit into the
TV Vertical Braces {27}, and a soundbar is not being used,
then the Brace Extenders {28} do not need to be installed.
Attach the TV Horizontal Brace {29} with Screws {18}.
Use the Vertical Braces to align the Extenders for
tightening if the TV is going to block access to the screws.
Then attach the Extenders to the Vertical Braces using
Screws {19} and Nuts {16}.
Measure the distance from the bottom of the Vertical
Braces {27} (not the Extenders) to the bottom of
television or Sound Bar.
Write down this distance to use in Step 9.
Use this distance in Step 9

This image at right shows that the further out a mantle extends, the more it will
interfere with the arc of the lowering TV. The chart below gives clearance heights
from the bottom of the TV to the top of various mantel sizes.
However, the MM8 Lift Housing {30} is often located even higher on the wall
than the TV. To locate the TV so it has enough clearance and doesn’t hit the
mantel, you will need to know how much higher the Housing is than the bottom
of the TV. Then you can locate the Housing on the wall.
NOTE: If there is extra space available, due to a high ceiling for example, then
these heights are only minimum requirements.

MantelMount RF Remote Control
MantelMount MM8 comes with an RF Remote Control. This Remote does not need to be
pointing at the mount in order to control the mount; in fact, the Remote will send commands to
the mount even from other rooms in the house. It is very important to operate the Remote only
when the mount is in sight. Otherwise, always store the Remote in a safe place away from
children.

This unique MantelMount feature will allow the mount to lower
to the the Memory 1 position whenever the TV is turned on,
and return home when the TV is turned off. The mount will do
this automatically without needing to use the Remote Control.
If the TV is plugged into the socket located onboard the MM800
instead of a wall outlet, MantelMount can monitor the power to
the TV and determine when it is turned on or off.
If this feature is not desired, simply plug the TV into a wall
outlet and operate the MM800 with the Remote Control.

OPTIONAL:
MM800 has a rear access hole that accepts threaded fittings for
standard 1/2” aluminum conduit. A licensed electrician can
hard wire the mount by splicing into the power cord.
Contact MantelMount for more information.
Hard Wire Conduit Access:
OPTIONAL:
MM800 includes brackets that make it easier to install horizontal 2x4 bracing inside the
wall. This is because all the attachment holes in the brackets can be reached for drilling
and screwing through the opening that is cut for the Lift Housing {30}, see FIG. A.
Notes: If the bracket is near the cutout opening, make sure to orient the attaching
hardware away from the opening so they do not interfere with the Housing. This
hardware is attached before the braces are installed into the wall, see FIG. B.
When cutting a center stud, measure 1.5” above and below the template mark before
the opening is cut out. Plunge cut through the stud at both locations and attach the cut
ends to the cross braces when they are installed, see FIG. C.

SURFACE MOUNT (non-recessed) installation using the
Horizontal Braces {31} to attach to existing wall studs:
The Horizontal Braces can reach studs that are up to
34 inches (875mm) apart. They attach flush to the back of the
Lift Housing {30}.
RECESSED installation using the Horizontal Braces {31} to
attach to existing wall studs:
The Horizontal Braces attach to the flange on the front of the
Lift Housing {30}. Use the included Template to mark the
location to cut the drywall. This installation is easiest when
there is no center stud that needs to be cut to make room.
SURFACE MOUNT (non-recessed) installation onto stone or
concrete walls using the six holes in the back of the Recess
Frame {30}. The lower Access Cover {32} must be removed to
access the lower holes.
The wall must be solid stone or concrete that can hold five times
the weight of all combined equipment. This surface must not be a
facade or non-structural material.
Use concrete anchors (not included) to attach mount to surface.
RECESSED installation using the included 2x4 Stud Brackets {53}.
When studs are far apart, when a center stud needs to be cut, or
when the cleanest look is desired, sections of horizontal 2x4 can
be installed through the cutout. They provide a solid structure for
the mount without the need for the Horizontal Braces. The mount
is attached with Lag Bolts through the holes in the front flange of
the Lift Housing {30}. Any studs that were cut can be reattached
to the new sections of 2x4.
Do Not overtighten Lag Bolts {13}. Tighten only until the
washers are firmly against the wall plate. Damage due to
overtightening can cause property damage or injury.

If the Auto Lowering Power Sensor (ALPS) feature is used, attach the
TV Power Cable as shown. The cable is plugged into the onboard
socket and quickly looped back away from the pinching area of the
TV Frame and the swivel portion of the mount. The socket must stay
centered between the two motor actuators. The cable can then be
looped again toward the TV with enough extra play to allow full
swivel to each side.
Keep all Cables
