MantelMount MM855 Installation Instructions Manual Download Page 4

Use a Vertical Brace {27} to determine if your television 
is a flat back or an irregular back. An irregular back will 
require spacers and longer screws to fill any spaces 
between the Vertical Brace and the TV.
The Braces must be parallel to your television screen. 

Choose the correct screw diameter and length for the TV. 
Hand-thread screw combination into the TV to ensure 
there is adequate thread engagement without hitting the 
bottom of threaded insert. Use only minimum amount of 
spacers (if required).

IMPORTANT INFORMATION: The Vertical Braces {27} are 
a fixed distance higher than the bottom of the Lift Housing 
Frame {30}. This relationship can be used to calculate 
most mounting situations such as centering the TV in an 
alcove or mounting the TV at a specific height on the wall.

If you measure the distance from the 
bottom of your TV (or Sound Bar) to the 
bottom of the Vertical Braces {27} (see: 
Page 5) you will automatically know the 
distance from the bottom of your TV to the 
bottom of the Lift Housing {30}. 

You can use this information to install the 
Lift Housing on the wall in order to locate 
your TV to any specific height you desire. 

Example: If the Vertical Braces are 
attached 10 inches from the bottom of the 
TV, then the bottom of the cutout opening 
should be 4 inches higher than where you 
want the bottom edge of the TV on the 
wall (10” - 6” = 4”).

If you are installing above a mantel, then 
your installation must still have the 
additional clearance for downward motion 
stated in the chart in Step 9
