Installation Instructions

INSTALLATION

The MSM1U/MTM1U/LSM1U/LTM1U 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 MSM1U/MTM1U, and 16"
or 24" on center for LSM1U/LTM1U) wall covered by drywall of
5/8" maximum thickness.
The MTM1U and LTM1U have brackets which allow the TV to
be tilted. The MSM1U and LSM1U have static brackets which
keep the TV in an upright position.

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 combined
weight of all components located on the mount, not to exceed
125 lbs (56.7 kg) for the MSM1U/MTM1U OR 200 lbs (90.7 kg)
for the LSM1U/LTM1U.
NOTE:
Proceed to either the Installing to a Wood Stud Wall

Installing to a Wood Stud Wall

1. Determine the center of the TV screen, and where it should

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 notches on mount (CC) with center of screen
marking to determine vertical center. (See Figure 1)
