NOTE: 

This mount comes with a variety of screw lengths and 

diameters to accommodate different display models. Not all of 
the hardware in the kit will be used. If you cannot find the 
appropriate screw size in the kit provided, consult with the 
manufacturer of your display or a professional installer.

Part 2 – Attaching the Mount Arms to the Display

IMPORTANT!

 Use extra care during this part of the installation 

to avoid damaging your display.

Part 1B – Mounting to the Wall (Concrete) (continued)

While another person holds the 
mount in place, mark four 
locations for securing the mount 
to the wall (see Fig. 3).

Set the mount aside and drill a 
3/8” hole at each marked location. 
Remove any excess dust from the 
holes.

Insert a concrete anchor (C) into 
each hole so that it is flush with 
the concrete surface (see Fig. 4). A 
hammer can be used to lightly tap 
the anchors into place if 
necessary.

Attach the mount to the wall with the arrow pointing up 
using the lag bolts (A) and washers (B) provided (see Fig. 3). 

Do not release the mount until all bolts are secure. 

Ensure 

that the mount remains level.

Attach the mount arms to the back of your display using 
the screws identified in steps 1 and 2

 

(see Fig. 5):

 

If you are using the M4 and M5 screws you will need to 
use the M5 Washers (F). If you are using M6 and M8 
screws, you will need to use the M8 washers (K).

If you are using the longer screws, you may also need to 
use spacers (L or M).

If the back of your display is flat and the mounting holes 

are flush with the surface, use the shorter screws (D, E G 

or H) from the hardware kit.

B

If the back of your display is curved or if additional space 

is needed between the display and the mount, use the 

longer screws.

2

Determine the correct diameter of screw to use by carefully 

trying one of each size (M4, M5, M6 and M8) from the 

hardware kit. 

Do not force any of the screws – if you feel 

resistance stop immediately and try a smaller diameter 

screw.

Determine the correct length of screw to use by examining 
the back of your display:

IMPORTANT! 

The latches must be closed and locked at 

all times to prevent the display from being accidentally 
knocked from the mount.

IMPORTANT! 

Never fully loosen or remove the level 

correction nuts.

To change the tilt angle of 
your display, have one 
person hold the display 
firmly in place while 
another person loosens 
the tilt knob (see Fig. 7). 
Once loosened, move your 
display to the desired 
position, and then 
re-tighten the knob. 

Do 

not release the display until the knob is fully tightened.

Swivel adjustments can be made by moving the display 
to the desired position. Be careful that fingers or cables do 
not get pinched when moving the mount.

Level correction 
adjustments can be made 
by rotating the display in 
the needed direction. If it 
is too difficult to turn the 
display or if the display 
does not stay in position, 
adjust the tension of the 
two wing nuts located 
behind the faceplate. 
Adjust the two nuts evenly (see Fig. 8). 

1

With the help of another person, carefully lift your display 
and place it on the mount. 

Do not release the display 

until the mount arms have 

securely hooked onto the 

mount.

Close the safety latch at the 
bottom of each arm. Each 
latch will automatically lock 
when fully closed (see Fig. 6).

Periodically clean your mount with a soft, dry cloth. Inspect 

all screws and hardware at regular intervals to ensure that 

no connections have become loose over time. Re-tighten 

as needed.

Cables can be routed through the channels located on the 
bottom of the mount. Make sure none of the cables can be 
pinched during operation of the mount.
