MINIMUM DISTANCE BETWEEN

Most customers want their TV mounted as close to the mantel as possible. If this
describes you, go directly to STEP 2.4.
However, if you want the TV higher on the wall (such as centered between the
mantel and ceiling) e.g. for extra space on the mantel for pictures or a center speaker,
continue to STEP 2.3.
Customer Support 1.800.897.9755 x1 suppor[email protected]

2.3
OPTIONAL Some customers want to place their TV higher than the
minimum distance from the mantel. Examples might be
centering your TV between the mantel and the ceiling/crown
molding, or to ensure extra space below the TV for pictures or a
center speaker.
To determine the precise vertical position of the Wall Plate (32},
use measurements already taken, then do some simple math
using the formulas below.
Gather measurements (write them down):
(A) Required Vertical Space PAGE 2
(B) TV Height PAGE 2
(C) Distance from STEP 2.1 PAGE 7
(D) Value from STEP 2.2 PAGE 7
Do some simple math (write down answers):
(E) = (A) – (B)
(F) = (E) + (C) – 3
Next, choose which option describes what you want to do:
1) If you want to center your TV between the mantel and
ceiling, use this calculation:
(H) = E – 2
2) If you know a specic number of inches you want between
your mantel and the bottom of your TV, write it below:
(H) =
Preferred Wall Plate location:
The calculation below will tell you how many inches above
your mantel to place the bottom of the Wall Plate for your
preferred TV position.
(I) = H + C – 3
Note: (I) should never be less than (D), the minimum Wall Plate
height, or greater than (F), the maximum Wall Plate height.
BONUS: To gure out how far below the mantel the bottom of
your TV will travel, solve this equation:
(J) = 27" – (H)
Place the Wall Plate higher on the wall.
8
2.4 2.5
DISTANCE
FROM 2.2 OR 2.3
Find the center of your mantel and the centers of two
studs.
Measure and mark the center line of the mantel onto the
wall with tape.
Next, use a stud nder to locate two studs, one on each
side of the centerline. (If you prefer to use one center
stud alone, see the troubleshooting section on page 18.)
Then, at the height from either STEP 2.2 or 2.3, locate the
center of the stud(s) by poking a sharp awl or nish nail
through the drywall to nd each stud edge. Mark these
center spots on the wall. Lag Bolts must be installed into
the CENTER of the studs in STEP 3.4.

TEMPLATE
STUD FINDER

Determine the positioning of the Wall Plates.
Position the LOWER SLOTS of the Template at the
appropriate distance from the mantel according to
placement preferences from either STEP 2.2 or 2.3. Use a
level to orient the Template.
Mark the center of the four slots along the marks for the
centers of the studs. This should create a cross mark for
each hole to drill.
Correctly orient a loose Wall Plate {32} to the LOWER hole
markings (with slots down) and then the UPPER holes
(with slots up). Determine if you can perfectly center
the Wall Plate over the mantel while reaching two studs,
and without interfering with a wall outlet. If there are no
issues, skip to STEP 3.1. Otherwise, proceed to STEP 2.6.

B. If necessary, move Wall
Plates to clear an outlet.
If a Wall Plate installation is
impeded by an electrical outlet
(or other) and professionally
relocating the outlet is impossible,
try one of these options:
• Move Wall Plates left or right
to clear the outlet. The Lifting
Arm can be attached anywhere
within the Wall Plates in order to
center the TV above the mantel,
making it adaptable for many
installation situations.
• Move Wall Plates up or down to
clear the outlet. As long as you
don’t place the LOWER Wall Plate
below the Minimum Distance
(STEP 2.2) or above the Maximum
Distance (STEP 2.3), MantelMount
will still function properly.
Simply move the Wall Plates up
or down enough to clear the
outlet, leaving them as close
as possible to the originally
planned vertical positions.
Next, move the Vertical Braces
{31} on the back of the TV using
the same number of inches used
to move theWall Plates (e.g., move
the Vertical Braces up 2" if the Wall
Plates were moved up by 2"). The
bottom of the Vertical Braces must
remain between 3 to 10 inches
from the bottom of the TV.
If outlet is directly behind the
Lifting Arm, the only solution is
to move the Wall Plates up.

The Wall Plates {32} don’t have
to center-align with the Lifting
Arm {35} or the mantel. As long
as the Wall Plates are bolted
into studs, the Lifting Arm can
slide within them, allowing
it (and therefore the TV) to
center-align with the mantel.
Slide the Wall Plates sideways
until they reach two studs, and
then mark the center line of
the wall onto the Wall Plates.
Remember to correctly orient
the Wall Plates as shown in
this image and keep track of
which Wall Plate is the UPPER
and LOWER (don’t accidentally
reverse them).

If the Lifting Arm is blocking a Wall Plate hole you
need to access:
Move the Wall Plates {32} to the left
or right of the desired position and
temporarily install it. Use four Lag Bolts
{17} to secure the Wall Plates to the
studs. This will allow you to pull the
Lifting Arm {35} down and install the
Safety Bolt (see STEP 4.1) in order to
access the blocked Wall Plate hole.
Then, remove Lag Bolts and reinstall the
mount in the desired
position.
For assistance, contact
Customer Support.
Attach Lifting Arm to Wall Plates.
If you arrived from STEP 2.5 then you can attach the
Lifting Arm {35} directly to the centers of the Wall Plates
(32}.
If you arrived from STEP 2.6 then you must align the
center of the Lifting Arm to the marks on the Wall Plates,
while orienting the Upper and Lower Wall Plate correctly.
Install four bolts {14} through the back channels of the
Wall Plates into the threaded holes of the Lifting Arm.
Tighten securely.

Customer satisfaction is our top priority!
Following are solutions for the most common installation challenges. For further assistance, visit www.mantelmount.com/troubleshooting or contact
Customer Support at 1-800-897-9755 ext.1 or suppor[email protected], Monday through Friday, 7am to 4pm PST.
NOTE: In rare cases, one troubleshooting adjustment may create the need for another. Be prepared for some trial and error.
The wall covering is
made of brick or stone.
MOUNT SPACE
MOUNT PERFORMANCE
It’s possible to install MantelMount by replacing the Lag Bolts {17} with concrete anchors of the same size if the
brick/stone is both rm and at least 1.5" deep. Bring the Lag Bolts to a hardware store for size reference. However,
we strongly recommend working with a concrete and masonry professional when working with uneven stone.
ISSUE
ISSUE
SOLUTION
SOLUTION (May require some trial and error to reach optimal performance.)
The drywall/stucco wall
covering is thicker than 5/8".
Please contact Customer Support for guidance before attempting installation.
A single wood stud is
centered on my wall.
It’s OK to mount the Wall Plates to a single stud by driving two Lag Bolts through the center of the Wall Plates and
into the center stud, as long as the Lifting Arm ends up positioned directly in front of the stud. Alternatively, for a
smaller footprint, replace the Wall Plates with the SSB40 Single Stud Adapter, available at MantelMount.com.
The Lifting Arm won’t
pull down in order to
insert the Safety Bolt.
The mount won’t remain
stationary anywhere
along the route of travel.
It will take some force to pull down the Lifting Arm when it’s in the raised position and there is no TV attached.
As long as the mount is securely attached to a stud(s) in the wall, it won’t break. First, make sure the TV Brace is
attached to the Lifting Arm (see Step 3.7).
Next, pull the Lifting Arm down: Stand in front of the mount, reach up and grasp the top or bottom of the TV
Brace with both hands, palms facing down. Move one foot back for leverage and straighten elbows. Then lean
back, bend both knees and elbows, and pull the mount out and down (see Step 4.1).
Make adjustments to the Lifting Force (see Step 5.1). The combination of the TV’s size and weight, installation
height and mantel depth may aect whether the TV can rest at various positions along the route of travel. What’s
most important is that the TV can comfortably pull down/lift up and stop at the optimal viewing height.
TV is dicult to pull down. Use the MantelMount Three-Step Pull-Down Technique:
1. Stand in front of the mount, arms extended with palms up and elbows straight.
2. Firmly grasp the lifting handles and lean back slightly with one foot forward and one foot back.
3. Step backward with forward foot to pull the mount away from the wall while placing downward
pressure on the handles (keep elbows extended).
If the mount is still dicult to pull down, review Step 5.1, make slight counterclockwise adjustments to the
Lifting Force, and try again. The goal is to adjust the Lifting Force just enough to comfortably pull the TV down
without overcompensating. If it becomes too easy to pull down, it may also become dicult to lift up. Give it a
few practice runs, but be prepared for a little trial and error.
TV is dicult to lift up. If the mount is relatively easy to pull down, slightly tighten it when it’s in the UP position. Review Step 5.1 to
make minor clockwise adjustments to the Lifting Force, then try lifting up the TV again. The goal is to adjust the
Lifting Force just enough to comfortably lift the TV without too much eort. However, if it becomes too easy to
lift up, it may become dicult to pull down.
If you are unable to nd a balance between ease of pulling down and lifting up, follow the instructions above
and focus primarily on making it easier to pull down. Then make adjustments to the Bottom Stop positions (see
Step 5.3). Lower the Bottom Stops to limit downward travel. The less downward travel, the easier it will be to lift.
TV is not lowering the full
vertical travel listed in the
specications.
If you can comfortably pull down and lift the TV but would like for it to drop below the lowest Bottom Stop
Position, remove the Bottom Stop Screws on each side (see Step 5.3); the TV will travel even lower. However,
proceed with caution. If the TV is above a mantel, removing the Bottom Stop Screws may cause the Lifting
Arm to hit the top of the mantel.

ISSUE
ISSUE
SOLUTION (May require some trial and error to reach optimal performance.)
POSSIBLE CAUSE HOW TO CHECK SOLUTION
TV is tilting forward
when in the UP position.
This is generally an indication that the Lifting Force is not set tight enough in the UP position (see Step 5.1).
Slightly turn the Tension Bolt clockwise and try again. The goal is to adjust the Lifting Force just enough for the TV
to no longer tilt in the UP position. Be careful not to set the Lifting Force too tightly in UP position or the TV may
not fully lower to the optimal viewing position.
The mantel, ceiling or
oor may not be level.
Wall Plates aren’t level.
The Bottom Stops
aren’t evenly set.
Post-Leveling
Adjustments haven’t
been made.
TV is heavier on
one side.
Vertical Braces aren’t
evenly attached.
Compare TV level with
that of the mantel and
oor.
Use a level on top of
Wall Plates to verify
that it’s not level.
Use a level to verify the
TV is level in the UP
position but not in the
DOWN position.
Use a level on top of the
TV to verify it’s leveled in
the DOWN position but
not in the UP position.
Use a level to verify the
TV is level in the UP
position but not in the
DOWN position.
Look at the back of
the TV and ensure that
the top of the Vertical
Braces are parallel to
one another.
1. Adjust until visibly satisfactory.
2. Pull down the TV.
3. Make Post Leveling adjustments (Step 5.6) and
match the level readings of the mantel with the TV.
4. Make additional adjustments as shown in Step 4.3
and Step 5.3 if needed.
1. Insert the Safety Bolt and Safety Nut (Step 4.1).
2. Detach the TV Brace from the Vertical Braces
(Step 4.4).
3. Remove electrical and signal cables (Step 4.5).
4. Remove the TV from the TV Brace (Step 4.2) and lay
TV face down on a blanketed surface (Step 1.1).
5. Remove the Vertical Brace(s) as necessary.
6. Reposition the Vertical Braces so that they are
properly parallel to one another, then repeat
Step 1, Step 4 and if necessary, Step 5.
1. Insert the Safety Bolt and Safety Nut (Step 4.1).
2. Detach TV Brace from Vertical Braces (Step 4.4).
3. Remove electrical and signal cables (Step 4.5).
4. Remove the TV from the TV Brace (Step 4.2) and
lay TV face down on a blanketed surface (Step 1.1).
5. Slightly loosen all four Lag Bolts (Step 3.4).
6. Adjust Wall Plates so that they are level.
7. Hold Wall Plates in level position and rmly tighten
the four Lag Bolts. Heed warning in Step 3.4.
8. Once the Wall Plates are level, repeat Steps 3, 4 and 5.
Follow the instructions in Step 5.3. Be prepared for
some trial and error. If adjusting the Bottom Stops
doesn’t solve the problem, try the solution below for
when a TV is heavier on one side.
Refer to Step 5.6 and make adjustments.
Attach a counterweight to the back of the TV.
Contact Customer Support for assistance.
TV is not level in the
