MantelMount has three dierent adjustments that must be made
after the installation is complete in order to operate properly.
The Centering Cams
automatically swivels the
TV to center while raising
to avoid permanent
obstacles.
The side-to-side swivel
stops are adjusted via
remote control and with
two screws so that the
TV does not swivel into
the mantel.
The bottom travel stop
is adjusted with the

If the lower VESA holes are less than 3" from the
bottom of the TV:
Connect the Vertical
Braces {31} through
the UPPER VESA
holes only, so that
the bottom of the
braces are between
3" to 10" from the
bottom of the TV. *
If the only option is
to attach the Vertical

Determine the minimum vertical position of the Wall Plate.
Use the Look-up Table below to nd the minimum distance between the mantel and
the bottom of the lower Wall Plate {32}. This will be the intersection of the distance
from STEP 2.1 and the mantel depth. Write the minimum distance in the box below.
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.
VALUE FROM
LOOK-UP TABLE
*If installing this mount with a MantelMount
RB100 Recess Box, the bottom of the Vertical
Brace must be 6”-10” from the bottom of TV
(or 6” from the bottom of the Soundbar if
one is installed).

Distance between
mantel and lower
wall plate holes
OPTIONAL Some customers want the TV centered between the mantel and the ceiling or crown molding. Others want enough space below the TV
for pictures or a center speaker.
The TV’s position on the wall is directly related to the placement of the lower Wall Plate. To determine exactly where to place the lower
Wall Plate, choose an option below that best describes your scenario and ll in the boxes.
NOTE: Distance “E” below must always be at least the minimum distance in STEP 2.2
Determine a higher vertical position of the Wall Plate.
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 “Mount Space” in the Troubleshooting Tips on
page 22.)
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 3.1.

Wall plate impeded by outlet.
BEFORE
If the wall plate sits directly behind lifting
arm wall plate must be moved up.
After
Wall Plate lowered to clear outlet.
After
Wall plate moved up to clear outlet.
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 two options:
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.
IMPORTANT: You must now move the Vertical Braces {31} on the back of the TV using the same number of inches
used to move the Wall Plates (e.g., move the Vertical Braces down 2" if the Wall Plates were moved down by 2" ).
The bottom of the Vertical Braces must remain between 3 to 10 inches from the bottom of the TV.
OPTIONAL: If you prefer to drill an access hole in your wall plate cover, the outlet may be placed within the
footprint of the wall plate.
Move the Wall Plates up enough to clear the outlet, leaving them as close as possible to the originally planned
vertical positions.
IMPORTANT: You must now move the Vertical Braces {31} on the back of the TV using the same number of inches

Swivel Safety Clutch
The Swivel on the mount has a friction clutch that
automatically disengages to avoid damage if the mount
swivels into something, or someone swivels the mount
manually. If that happens the swivel will be out of position
and the swivel will not work as expected. The swivel needs
to be recalibrated right away to avoid damage.
To recalibrate Auto-move the mount to the top position:
Press Run
Press within 3 seconds
The mount will automatically move to the top position and
recalibrate. You can also run Reset Function to recalibrate.
Note: If clutch is engaged the mount may swivel a little when
coming down, to fix this; manually center mount at zero degree
swivel by rotating TV with hands and over-riding clutch. Mount is
at zero degrees swivel after you recalibrate (drive the mount to the
top position), then move the mount straight down.

the Lifting Mechanism can cause bodily injury!
Pinching and Crushing Hazard.
The wall mount actuation is very strong, do NOT run the
mount when anyone is near the mount. Do NOT have
any part of the body in the mount or between the TV and
Wall. The Mount will keep driving until someone pushes
another button on the remote to stop it. When working on
the mount unplug the power.

Carefully slide the TV sideways, if required, until it is
balanced and horizontal, up to a MAXIMUM OF 2 INCHES
left or right.
The TV would only need to be moved o-center if it has an
unbalanced weight. These are usually older, heavier TVs.
If the TV needs to be moved sideways and is visually too
much o-center above the mantel, remove the TV and
relocate the Wall Plate {32} an equal distance but in the
opposite direction of the TV to compensate.
4.3
Attach the electrical and signal cables to the TV.
Run signal cables through open loop. Give each segment
of the cables extra length so that they are not stressed or
kinked when the mount moves.
Ensure that cables do not get pinched within the Lifting
Arm when the TV is raised.
Reference Only: This is one possible conguration for
the signal cables. Each segment of the cables has extra
length so that the cables are not stressed or kinked when
the mount is moved.
Attach cable ties to lower arm.
Shown below is the easiest way to attach cables. Use the
included Cable Ties {24} to attach cables so they attach to
the underside of the Lower Arm, making a gentle loop.
Cables should be long enough to accommodate the
extension and swivel of MantelMount. Check all ranges of
motion before tightening the Cable Ties.
