The plastic gears in my Sears chain drive opener failed again, so I chose to replace the opener with a new Genie screw drive opener. After assembling the new opener and taking measurements, I discovered there would be insufficient clearance between the rail and the door as it opened, even if I mounted everything as high as the ceiling (my ceiling is 8 ft. and my door is 7 ft.).
Upon contacting Genie customer service, the agent said I would have to purchase a "low headroom kit". Anybody had this experience? Any suggestions?
