Torsion Springs: Torsion springs are mounted above the garage door, typically on a metal shaft. They work by winding and unwinding, storing and releasing energy as the door moves. When the door is closed, torsion springs are in a state of high tension. As the door is opened, the springs unwind, releasing stored energy to assist in lifting the door. When the door is closed again, the springs wind back up, storing energy for the next cycle.

Torsion springs are considered safer than extension springs because they are typically installed on a shaft, reducing the risk of them snapping and causing injury. They are also known for providing smoother and more controlled door movement.

Extension Springs: Extension springs are located on either side of the garage door, often parallel to the tracks. They work by stretching and contracting to help lift and lower the door. When the door is closed, extension springs are fully extended, and as the door is opened, they contract, storing energy. When the door is closed, they extend again, providing the force and energy required to raise the garage door.

Identifying Torsion and Extension Springs: To identify the type of springs your garage door uses, you can look for the following visual cues:

    Location: Torsion springs are typically found above the garage door, mounted horizontally on a metal shaft. Extension springs, on the other hand, are located on both sides of the door, running parallel to the tracks.

    Appearance: Torsion springs resemble tightly wound coils, while extension springs look like elongated, stretched-out springs.

    Safety Cables: Extension springs are often equipped with safety cables that run through the spring itself. These cables help contain the spring in case of breakage, preventing it from flying across the garage.
