Most traditional garage door openers mount on the ceiling with a track. If you've got an extremely high or low ceiling, did you know that you can get a side mounted garage door opener for not much more money? If you've got restrictions on a standard motor, why not try a side mounted jackshaft garage door opener. Even Jay Leno uses one in his garage!
