Canopy Up & Over
The canopy garage door is the simplest and most common design and type of up and over 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 it is the easiest design to install. The door is balanced and assisted by torsion springs positioned above the door panel on the head of the fixing frame. 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 electric motor automated although with the use of a good quality 'bow arm converter' and a reasonably powerful operator this type of door can be automated successfully, Ask us at the garagedoorspecialist for any advice
The retractable garage door is becoming the more popular type of up and over garage door mechanism in the UK, its name derived from the garage door panel retracting fully into the garage when open. It is the mechanism that will convert easily and safely into remote control electric operation with the least equipment required. The drive-through width on a retractable mechanism is reduced compared to the Canopy design as the lifting arms sit in between the sub-frame when the door is opened so be careful when limited for width that you do not restrict access too much.
The retractable mechanism can take much heavier loads with tension springs at the sides easily increased in size and strength if required. It is generally considered smoother and easier to operate.
