Up and Over Garage Doors Canopy and Retractable Door Gear
Up and over garage doors are available with 2 main types of door gear. The door gear is the parts and mechanism that allow the door panel itself to move.
Canopy Door Gear
Canopy doors do not need any tracks going back into the garage and they offer pretty much the full available drive through width as the mechanism does not take up any additional space in the opening.
Canopy door gear is usually only available on doors up to 8ft wide as this type of mechanism does not work as effectively with heavier doors. Although some manufacturers including Henderson garage doors, did at one stage introduce some larger models with reinforced canopy gear.
Canopy doors can be automated; however, this usually requires the use of a canopy ‘bow arm’ conversion kit that reduces the drive through height of the door and increases the cost.
Retractable Door Gear
The weight of the door is usually counterbalanced with springs attached to arms on either side of the garage door which does slightly reduce the drive though width.
Retractable door gear is much more robust and the side spring mechanism can support the heavier double size doors that are wider than 8ft.
Retractable up and over garage door gear is a very reliable, robust and smooth operating mechanism that can easily be automated without the need for any additional conversion equipment.
