Position and Mount the Garage Door Opener

NOTE: 

For additional mounting options refer to the accessories page.

1. 

Close the garage door completely.

2. 

 Slide the garage door opener onto the end of the torsion bar. If the torsion bar is too 
long or damaged, you may need to cut the torsion bar. 

 

Ensure the collar does NOT touch the bearing. 

3. 

 Use a level to position and vertically align the garage door opener. Verify the 
mounting bracket is located on a solid surface such as wood, concrete or door/fl ag 
bracket. If installing on drywall, the mounting bracket MUST be attached to a stud.

4. 

 When the garage door opener is properly aligned, mark the mounting bracket holes. 
If necessary, tighten collar screws on the torsion bar to hold garage door opener in 
place while marking holes.

 NOTE: 

The garage door opener does not have to be fl ush to wall.

5. 

 Remove the garage door opener from torsion bar. Drill 3/16 inch pilot holes at the 
marked locations. Drill through metal door rail plates if necessary.

6. 

 Slide the garage door opener back onto the torsion bar until pilot holes align with 
bracket. 

7. 

 Tighten the 2 square head set screws on the torsion bar. For a hollow torsion bar, 
tighten screws 3/4 - 1 full turn after making contact with the bar. For a solid shaft 
torsion bar, tighten screws 1/4 - no more than 1/2 turn after making contact with 
the shaft. If installing on a keyed torsion bar, DO NOT tighten the screws into the 
keyway.

8. 

 Secure the mounting bracket to the wall and to the garage door opener. Use the 
14-10 x 2" screws to secure the mounting bracket to the wall.

To prevent possible SERIOUS INJURY 
or DEATH:
• 

 Concrete anchors MUST be used if 
mounting bracket into masonry.

• 

 NEVER try to loosen, move or 
adjust garage door, springs, 
cables, pulleys, brackets or their 
hardware, ALL of which are under 
EXTREME tension. 

• 

 ALWAYS call a trained door 
systems technician if garage door 
binds, sticks or is out of balance. 
An unbalanced garage door might 
NOT reverse when required.

• 

 Garage door opener MUST be 
mounted at a right angle to the 
torsion bar to avoid premature 
wear on the collar.
