Exploring Overhead
Garage Door Spring Types
Extension vs. Torsion
Overhead garage doors typically utilize two main types of springs: extension springs and torsion springs.
These springs play a crucial role in counterbalancing the weight of the garage door, making it easier to open and close manually or with a garage door opener.
- Extension Springs
Extension springs are mounted above the horizontal tracks on both sides of the garage door. They stretch and contract as the door opens and closes, providing the necessary force to lift and lower the door. Extension springs are usually installed in pairs and are connected to safety cables to prevent injury in case of spring failure. While extension springs are commonly used in residential garage doors, they can take up more space in the garage compared to torsion springs.
- Torsion Springs
Torsion springs are mounted above the garage door opening on a metal shaft. They are wound tightly to store mechanical energy, which is released when the door is opened. Additionally, torsion springs are considered safer because they are contained within a metal tube, reducing the risk of injury in case of spring failure.
Both extension and torsion springs have their advantages and disadvantages, and the choice between them depends on factors such as the size and weight of the garage door, available space, and personal preference.
