The canopy garage door is the simplest and most common type of garage door mechanism, its name derived from the fully opened garage door panel protruding about a third forward of the sub frame to form a canopy. It gives the maximum drive-through width when open and is the easiest to install. The door is balanced and assisted by torsion springs positioned above the door panel on the head of the fixing frame lifting the door panel by a pair of cables attached to a roller either side of the door.
The canopy door mechanism is generally only available up to 8 feet (2438mm) wide. It is not generally used if the garage door is to be automated. For automation we would recommend a retractable garage door.
