I'm having a garage door installed - 9'6" tall and 10' wide - and I'm wondering: how much clearance do I need from the top of the tracks to the ceiling for the installation of garage door opener, such as one made from Sears? The height of the door is 9'6", and the ceiling is
10' 11". Will an opener fit, and if not, can the horizontal tracks be angled downwards (from the face of the door to the middle of the garage) a few inches to make room for the opener.Thanks in advance.
