INSTALLATION
The MSA1U/MTA1U/LSA1U/LTA1U mounts are designed to be
mounted to a bare 8" concrete, 8"x8"x16" concrete block; or
2" x 4" wood studs (16" on center for MSA1U/MTA1U, and 16"
or 24" on center for LSA1U/LT A1U) wall covered by drywall with
5/8" maximum thickness.
The MTA1U and LTA1U have brackets which allow the TV to be
tilted. The MSA1U and LSA1U have static brackets which keep
the TV in an upright position.
Locate Mounting Site
WARNING:
MOUNT FALLING CAUSING SEVERE PERSONAL INJURY
OR DAMAGE TO EQUIPMENT! It is the installers responsibility
to make certain the structure to which the mount is being
attached is capable of supporting five times the combined
weight of all components located on the mount, not to exceed
125 lbs (56.7 kg) for the MSA1U/MTA1U,
for the LSA1U/LTA1U.
NOTE: Proceed to either the Installing to a Wood Stud Wall
section or the Installing to a Concrete Wall section.
Installing to a Wood Stud Wall
1. Determine the center of the TV screen, and where it should
be located on the wall.
2. Locate the closest stud to the left and right of the selected
location.
IMPROPER INSTALLATION CAN LEAD TO
OR
200 lbs (90.7 kg)
5. Using a level, mark the wall on each stud to attach the
mount through the upper mounting slots. (See Figure 2)
6. Drill one 7/32" (5.5mm) pilot hole in each stud.
7. Partially install two 5/16 x 2-1/2" flanged lag bolts (N) into
pilot holes but do not tighten to wall.
8. Hang mount (Z), aligning upper mounting slots over lag
bolts and adjust side-to-side for proper location.
9. Place one slotted washer (Q) over each flanged lag bolt.
(See Figure 2)
10. Tighten lag bolts to secure mount (Z) to wall at upper
mounting slots.
NOTE: If the screen area lies over a stud, use that stud and the
stud to either the left or right of it.
3. Line up the diamond shapes on mount (Z) with center of
screen marking to determine vertical center. (See Figure 1)
4. Measure up 7" (177.8mm) from the center point to mark
location of the upper mounting slots. (See Figure 1)
Figure 2
11. Mark the attachment points for the lower mounting slots,
making sure the attachment points are located on the studs.
(See Figure 2)
12. Drill 7/32" (5.5mm) pilot holes at markings for lower
mounting holes. (See Figure 2)
13. Use two 5/16 x 2-1/2" flanged lag bolts (N) and two 5/16"
slotted washers (Q) to attach the mount to the wall through
the lower mounting holes. (See Figure 2)
14. Slide rails to approximate center of screen location.
15. Proceed to Attaching Interface Brackets to Screen
section.

Installing to a Concrete Wall
1. Determine the center of the TV screen, and where it should
be located on the wall.
2. Line up the diamond shapes on mount (Z) with center of
screen marking to determine vertical center. (See Figure 1)
3. Measure up 7" (177.8mm) from the center point to mark
location of the upper mounting slots.
4. Using a level, mark the wall through both upper mounting
slots. (See Figure 3)
13. Use two 5/16 x 2-1/2" flanged lag bolts (N) and two 5/16"
slotted washers (Q) to attach the mount to the wall through
the lower mounting holes. (See Figure 3)
14. Slide rails to approximate center of screen location.
Attaching Interface Brackets to Screen
1. Align the center of the bracket (V and W or X and Y) with
center of screen. (See Figure 4)
NOTE: The diamond-shape holes in the bracket correspond to
the center of the mount.
Figure 3
CAUTION: MINIMUM HORIZONTAL DISTANCE
BETWEEN WALL BRACKETS IS 16" (406.4mm). Do not
place mounting brackets closer together than 16" (406.4mm).
5. Drill one 3/8" x 3-1/2" (9.5mm x 88.9mm) pilot hole at each
marking.
6. Install an anchor (P) into each pilot hole using a hammer,
making sure that the anchor is flush with the wall.
7. Partially install two 5/16 x 2-1/2" flanged lag bolts (N) into
pilot holes but do not tighten to wall.
8. Hang mount (Z), aligning upper mounting slots over lag
bolts and adjust side-to-side for proper location.
9. Place one slotted washer (Q) over each flanged lag bolt.
(See Figure 3)
10. Tighten lag bolts to secure mount (Z) to wall at upper
mounting slots.
11. Mark the attachment points for the lower mounting slots,
making sure the attachment point s are located on the studs.
(See Figure 3)
12. Drill 3/8" x 3-1/2" (9.5mm x 88.9mm) pilot holes at markings
for lower mounting holes. (See Figure 3)

Figure 4
WARNING: IMPROPER INSTALLATION CAN LEAD TO
DISPLAY FALLING CAUSING SERIOUS PERSONAL
INJURY OR DAMAGE TO EQUIPMENT! Using screws of
improper size may damage your display. Properly sized
screws will easily and completely thread into display
mounting holes. If spacers are required, be sure to use longer
screws of the same diameter.
2. Select correct screws, nesting spacers (if necessary) and
universal washers (if required) from the hardware bag (A-M)
and attach brackets to back of screen. (See Figure 4)
IMPORTANT ! : The M8 screws do NOT require a
washer. Use the universal washer (MB) only with M4, M5
and M6 screws.

Switching Interface Brackets (Optional)
If an installation situation makes adjusting the location of
interface brackets necessary, there are several options.
1. The wall brackets may be adjusted side to side at the point
of attachment. (See Figure 6)
2. The location of the left and right interface brackets (V and W
or X and Y) may be switched, with the knobs on the MTA1U/
L TA1U interface brackets (X and Y) facing the inside of the
mount. (See Figure 6)
3. If necessary, the tilt interface bracket knobs may be
switched to allow the interface brackets (X and Y) to be
reversed. (See Figure 7)
a. Remove display from mount.
b. Remove interface brackets from display.
c. Hold the right interface bracket horizontally, tightly
gripping it so that spacers do not move.
d. Remove the knob and screw.
e. Replace the knob and screw in the opposite order, with
the knob on the inside of the bracket.
f. Switch the right interface bracket to the left side of the
wall mount.
g. Repeat Steps 3c through 3f with the left interface
bracket.
