STEP 15 – Attaching an Automatic Opener
IMPORTANT: To avoid damage to your door, you must 
reinforce the top section of the door in order to provide a 
mounting point for the opener to be attached. Refer to the 
section of this manual titled Reinforcing the Top Section on 
page 14 for specic instructions. Failure to reinforce the door 
as illustrated will void the warranty on your door.
To avoid risk of strangulation or personal injury to 
children, if your door has a pull rope, you must remove 
the pull down rope when you install an automatic garage 
door opener.
IMPORTANT: When installing an automatic garage door 
operator, make sure to follow manufacturer’s installation and 
safety instructions carefully. Remove the pull down rope and 
unlock or remove the lock. If attaching an operator bracket 
to the wooden anchor pad, make sure the wood anchor pad 
is free of cracks and splits and is rmly attached to the wall. 
Always drill pilot holes before attaching lag screws.
The operator arm will usually be attached to the vertical 
reinforcement member at roughly the same height as the top 
roller of the door. Attach the opener arm to the reinforcement 
as shown in Figures 15-B to 15-D. To prevent the top of the 
door from bending, the opener rail should be mounted no less 
than 2" and no greater than 5" from the face of the door with 
the door in the open position (FIG. 15-A). Additionally, when 
the door is closed, the portion of the operator arm attached to 
the door should be at angle of approximately 60 degrees from 
the vertical (FIG. 15-B).
