INSTALLATION
The LTM and LSM have been designed to be mounted directly onto either a wood stud or concrete wall. The LTM has brackets which allow the TV to be tilted. The LSM has static brackets which keep the TV in an upright position.
Locate Mounting Site

WARNING: IMPROPER INSTALLATION CAN LEAD TO 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 weight of the LTM or LSM and all attached equipment not to exceed 200 lbs (90.7 kg).
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
- Determine the center of the TV screen, and where it should be located on the wall.
- Locate the closest stud to the left and right of the selected location.
NOTE: If the screen area lies over a stud, use that stud and the stud to either the left or right of it.
- Line up the notches on mount (A) with center of screen marking to determine vertical center. (See Figure 1)
- Measure up 7-1/2" (190.5mm) from the center point to mark location of the upper mounting slots.

Figure 1
- Using a level, mark the wall on each stud to attach the mount through the upper mounting slots. (See Figure 2)

WARNING: ELECTRICAL SHOCK HAZARD! CUTTING OR DRILLING INTO ELECTRICAL CORDS OR CABLES CAN CAUSE DEATH OR SERIOUS PERSONAL INJURY! ALWAYS make certain area behind mounting surface is free of electrical wires and cables before drilling or installing fasteners.

WARNING: EXPLOSION AND FIRE HAZARD! CUTTING OR DRILLING INTO GAS PLUMBING CAN CAUSE DEATH OR SERIOUS PERSONAL INJURY! ALWAYS make certain area behind mounting surface is free of gas, water, waste, or any other plumbing before cutting, drilling, or installing fasteners.
- Drill one 7/32" (5.5mm) pilot hole in each stud.
- Use two 5/16 x 2-1/2" lag bolts (QC) and two 5/16" flat washers (QB) to attach top of mount (R) to wall. (See Figure 2)

Figure 2
- Mark the attachment points for the lower mounting slots, making sure the attachment points are located on the studs. (See Figure 2)
- Drill 7/32" (5.5mm) pilot holes at markings for lower mounting holes. (See Figure 2)
- Use two 5/16 x 2-1/2" lag bolts (QC) and two 5/16" flat washers (QB) to attach the mount to the wall through the lower mounting holes. (See Figure 2)
- Slide rails to approximate center of screen location.
Installing to a Concrete Wall
- Determine the center of the TV screen, and where it should be located on the wall.
- Line up the notches on mount (A) with center of screen marking to determine vertical center. (See Figure 1)
- Measure up 7-1/2" (190.5mm) from the center point to mark location of the upper mounting slots. (See Figure 1)
- Using a level, mark the wall through both upper mounting slots. (See Figure 3)

CAUTION: MINIMUM HORIZONTAL DISTANCE BETWEEN WALL BRACKETS IS 12" (304.8mm). Do not place mounting brackets closer together than 12" (304.8mm).

WARNING: ELECTRICAL SHOCK HAZARD! CUTTING OR DRILLING INTO ELECTRICAL CORDS OR CABLES CAN CAUSE DEATH OR SERIOUS PERSONAL INJURY! ALWAYS make certain area behind mounting surface is free of electrical wires and cables before drilling or installing fasteners.

WARNING: EXPLOSION AND FIRE HAZARD! CUTTING OR DRILLING INTO GAS PLUMBING CAN CAUSE DEATH OR SERIOUS PERSONAL INJURY! ALWAYS make certain area behind mounting surface is free of gas, water, waste, or any other plumbing before cutting, drilling, or installing fasteners.

Figure 3
- Drill one 5/16" (7.9mm) pilot hole at each marking.
-
Install an anchor (QA) into each pilot hole using a hammer, making sure that the anchor is flush with the wall.
-
Use two 5/16 x 2-1/2" lag bolts (QC) and two 5/16" flat washers (QB) to attach top of mount (R) to anchors in wall.
- Mark the attachment points for the lower mounting slots. (See Figure 3)
- Drill one pilot hole at each marking for lower mounting holes. (See Figure 3)
- Install an anchor (QA) into each pilot hole using a hammer.
- Use two 5/16 x 2-1/2" lag bolts (QC) and two 5/16" flat washers (QB) to attach the mount to the wall through the lower mounting holes. (See Figure 3)
- Slide rails to approximate center of screen location.
Attaching Interface Brackets to TV
- Align the center of the bracket (W and X or Y and Z) with center of screen. (See Figure 4)
NOTE: The diamond-shape hole in the bracket corresponds to the center of the mount.
![[Brackets W and X shown] Pull strap Center of bracket](/content/2026/05/1141073/images/79413415a7863e7b574d1430861d2c4c7d3e602e0e8c81149345262e0da47058.jpg)

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.
- Select correct screws, spacers (if necessary) and universal washers from the hardware bag (A-N) and attach brackets to back of screen. (See Figure 4)
Switching Interface Brackets (Optional)
If an installation situation makes adjusting the location of interface brackets necessary, there are several options.
- The wall brackets may be adjusted side to side at the point of attachment. (See Figure 5)
- The location of the left and right interface brackets (W and X or Y and Z) may be switched, with the knobs on the LTM interface brackets (Y and Z) facing the inside of the mount. (See Figure 5)
![Knobs [Brackets Y and Z shown]](/content/2026/05/1141073/images/4bf04d54804f9524c37e7f8ebe1a6b82c5f19d8bb735ca431501c995a340b9f9.jpg)
Figure 5
- If necessary, the tilt interface bracket knobs may be switched to allow the interface brackets (Y and Z) to be reversed. (See Figure 6)
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, washer and screw.
e. Replace the knob, washer 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.

Figure 6
Attaching Screen to Wall Mount
- Attach wall bracket caps (V) to top and bottom of both wall brackets. (See Figure 7)

Figure 7
- Adjust Velcro® pull strap (if necessary) so it does not extend beyond bottom of screen. (See Figure 8)
NOTE: Do NOT allow both interface brackets (W and X or Y and Z) to be located on same side of wall bracket. (See Figure 8)
NOTE: NEVER place both interface brackets (W and X or Y and Z) to one side of the wall mount center line! (See Figure 8)
![Center Line (CL) Pullstrap ▲ NEVER place both interface brackets to one side of the wall mount center line (CL)! ▲ Both interface brackets must NEVER be located to one side of the wall brackets!

-
Route cables between wall and bars.

CAUTION: PINCH POINTS! Keep fingers, hands and cables out of pinch point areas.
- Pull downward on the pullstraps and swing inward toward wall, latching interface brackets to lower bar and locking bottom of screen to the mount. (See Figure 9)
