Measure to locate the center of the door and mark 
a vertical pencil line on the mounting surface above 
the door, to indicate the center line of the door. Then, 
measure from the center of the bearing, in one of 
the end bearing brackets, DOWN to the top of the 
door. Using that dimension, measure UP from the top 
of the door and mark a horizontal pencil line on the 
mounting surface, intersecting the vertical pencil line. 
Now align the edge of the center bearing bracket 
along the vertical pencil line on the mounting surface. 
Center the bearing bracket on the horizontal line. 
This will ensure the torsion tube is level between the 
center and end bearing brackets. Attach the center 
bearing bracket, in this location, to the mounting 
surface, using (2) 5/16” x 1-5/8” lag screws and (1) 
5/16” x 2” tamper-resistant lag screw.
