What can you do if the garage ceiling is too low for the garage door
opener?



You have several options. If your door uses standard tracks, you can replace
them with tight radius tracks. This will lower the height of the upper track.
Use an opener like a Genie Pro, which only requires about 3 inches over the
highest part of the door travel.

Or, you can buy a wall-mount gargage door opener like this one at Wayne Dalton:
