Up & over garage doors are still by far the most popular type of garage door. Up & over doors come in two types – canopy and retractable.
A retractable garage door has horizontal tracks that extend back into the garage. The tension springs are on the frame legs. This type of door is suitable for both electric and manual operation.
A canopy type garage door has vertical tracks on the frame legs, a torsion spring along the frame head, and is attached to the door by cables which wind up on drums or cones. The canopy type garage door is suitable only for manual operation.
