never exceed 110° F.
110°F
MAX.
Mantle must not extend from mounting surface
more than 19 inches (22 inches for non-recessed
C
installations). MantelMount can not extend past a mantel
larger than 19 inches. Larger mantels will also reduce the
amount of side-to-side swivel.
D
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.

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

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.

PAGE 4 MantelMount MM750
The Vertical Braces {27} are always mounted higher than
5 6
the bottom of the TV. However, the Brace Extenders {28}
will be mounted one of two ways:
Without a Sound Bar - The Brace Extenders are
installed within a few inches above the bottom of 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}.
{27}
Vertical Braces:
Always higher
than the bottom
of the TV
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.
If the holes on the TV are lower than the braces, install the
lower screws through the Brace Extenders {28} using the
included Spacers {12}.

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 MM750 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.
If mantle extends:
Less than 10 inches Add 5 inches
10 - 14 inches

Installation Options: Surface Mount
SURFACE MOUNT (non-recessed) installation using Horizontal Braces {31}
to attach to existing wall studs, on top of existing drywall.
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}.
SURFACE MOUNT (non-recessed) installation onto
stone or concrete walls using the six holes in the back
of the Lift Housing {30}.
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 the Lift
Housing to the surface.

RECESSED installation using the Horizontal Braces {31} to attach to existing wall studs:
Not Included
The Horizontal Braces attach to the flange on the front of the Lift Housing {30}.
The Braces can be located off-center to the Housing, if needed, to reach the nearest stud.
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.
Paintable Wall Covers {25} can be snapped onto the Horizontal Braces.

MantelMount MM750 PAGE 7
Installation Options: Recessed using 2x4 Stud Brackets {21}
MM750 includes brackets that make it easier to install horizontal
pieces of 2x4 bracing inside the wall. This is because all of the
attachment holes in the Brackets can be reached for drilling and
screwing simply by reaching through the opening that is cut for
the Lift Housing {30}, see FIG. A.
When wall studs are far apart, or 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 {31}. The mount is attached with Lag Bolts through the
holes in the front flange of the Lift Housing {30}.

Note: 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 Lift
Housing {30}. This hardware is
attached before the braces are
installed into the wall, see FIG. B.
Cutting a Center Stud:
When cutting a center stud, measure 1.5” above and below the
template mark before the opening is cut out. The drywall will hold
the stud in place while it is cut. Plunge cut through the stud at
both locations and attach the cut ends to the cross bracing when
they are installed, see FIG. C.

Use the Template to mark the location of the Housing
according to the height from step 9. Make sure the
Template is level and centered. MantelMount is located in
the same spot for all installations.
Install the Lift Housing {30}
Locate, Mark, and Pre-Drill Studs in the Wall. All holes
must be pre-drilled with 7/32” drill bit to a depth of 2.5
inches (65mm) including wall covering. Note: Wall covering
(drywall) must not exceed 5/8” thickness.
If you are surface mounting, you will only need to mark
the corners, but for recess mounting you will trace the
entire template to cut out the drywall.

Pull the Safety Braces out to the ready position as shown. You might
need to flex them over the screws. Do not bend the Safety Braces.
Firmly and slowly pull down the Arm until the Lifting Mechanism is in a
horizontal position. The second person must swing the Safety Braces
upward until they grab the crossmember of the Upper Arm.
The Lifting Mechanism should stay at a horizontal position.

WARNING:
DO NOT put hands into Lifting Mechanism while operating
the mount. Severe Injury can occur due to pinching or
crushing. Always use the Safety Braces when working
near or inside MantelMount.
Install the TV Frame {26} using 4 Screws {20} and
Washers {11}. These screws can also be used to fine
tune level the TV. Always remember to tighten.

{26}
THIS STEP REQUIRES TWO PEOPLE
Carefully hang the Television onto the TV Frame
making sure that both hooks on the Vertical
Braces {27} engage the TV Frame.
DO NOT allow the Television to drop far enough
to cause the Lifting Mechanism to hit the mantle.
MantelMount comes pre-adjusted to reduce the
possibility of contacting the mantle, but you
should always be prepared to remove the
television at this stage to make the proper
correction.
If the Lift Housing {30} appears to be too close
to the mantle, remove television. Go to STEP 17
and make an adjustment to the Bottom Stop
position. Repeat this process until the Lifting
Mechanism is a safe distance from the mantle
when the TV is installed.
Some older TVs are not weight balanced. If the
TV is much heavier on one side, slide the TV
slightly sideways to balance and level the TV.
Attach with 4 Screws {18}.
{18}
PAGE 10 MantelMount MM750
Adjusting for Television weight: With Safety Braces in place, use a socket
16
wrench with an extension to adjust the long bolts inside the Lift Housing {30}. Take
turns adjusting each side so they stay relatively even with each other.
Turn the bolts clockwise (AS SHOWN BELOW) to pull the Gas Springs down and
increase the lifting force for heavy TVs, or turn counter-clockwise for lighter TVs.
This adjustment can take several turns. Reference the sticker scale on each side for
the weight of the TV. Each scale represents the TOTAL WEIGHT of the TV.
Adjust the bolt until the TV gently stays in the lowered position. When the mount
moves with a neutral feel within the Safety Braces, un-latch the Safety Braces and
check the mount operation throughout the full range of motion.
(TV and some components are not shown in these images for clarity.)

MantelMount MM750 PAGE 11
Adjusting the Hard Stops for Range of Motion:
Adjusting the Bottom Stop
17 18
Position:
Loosen the Locknuts and adjust
the Bottom Stop screws to the
desired stopping position.
There are two screws underneath
the Lifting Mechanism. Turn these
screws inward until they tighten at
the desired lower position.
Tighten both locknuts after the
adjustments are made.
Adjusting the Side Swivel Stop
Positions:
Loosen the Locknuts and adjust the
Swivel Stop screws to the desired
stopping positions, both left and
right.
Tighten both locknuts after the
adjustments are made.
Note: If no swivel is desired, it may
be necessary to remove the locknuts
and re-attach them on the other side
of the Swivel Bracket so that the
Screws can be threaded out to their
maximum length.
Removing unwanted Tilt:
19 20
The TV should be fairly vertical in the up position and
parallel to the wall. If the TV is tilted slightly downward,
back out the adjustment screw slightly as shown.
Tighten the locknut after the adjustment is made.
If cables are attached using the Anchors {14}, ensure that
cables are not near the pinching area of the TV Frame and
swivel portion of the mount. If cables are near the swivel,
loop them away from the pinch area securely.
Attaching Cables:
Keep all Cables
below pinch area
Anchor
{14}
Cable Ties
{15}
PAGE 12 MantelMount MM750
Reference Only: This is one possible configuration for the signal cables. Each segment of the cables
21
has extra length so that the cables are not stressed or kinked when the mount is moved.
Ensure that cables do not get pinched between brackets when the mount is raised.
!
CAUTION:
Never release the handle before it is fully upright.
MantelMount is strongest in the top position, and
allowing it to slam closed can damage televisions.
Always control the lifting process.
!
CAUTION:
Never allow small children to play around or
operate MantelMount. Property damage or
personal injury can occur.
