This type of garage door normally has rollers running vertically on the door posts and large spring across the top of the door.
When fully open, the door does not retract all the way in to the garage but leaves a section creating a canopy in front of the garage.
These doors do not have horizontal runners into the garage.
For single or double canopy garage doors we would recommend you use the LM5580A-2 Garage Door Opener with a Canopy Arm Adapter.
Other openers can be used with a canopy adapter, although it is not recommended as it can cause problems.
This type of garage door normally runs on a track along the roof of your garage. Usually large springs can be seen on both sides of the door.
When fully open the door usually retracts all the way inside the garage.

Although retractable doors are usually contained inside the garage space when opened, some may extend beyond the door opening, similarly to the way a canopy type door does.
In this case, another way to distinguish between Canopy and Retractable type doors is to identify the placement of the door’s springs. If the spring is above the door, it is a canopy type door. If the springs are beside the door, it is a retractable type door.
