Torsion and Extension Springs

Torsion and extension springs are the most important component of garage door operation, and both create the necessary counterbalance that allow garage doors to operate smoothly.

Torsion springs – These wind around a shaft which is attached to the garage door via cable drums to exert a torque force that causes rotation. These springs apply constant energy so that garage doors open and close at a controlled, continual motion. Torsion springs either wind, allowing the garage door to shift from an up and open position to closed, or unwind to open the door. The size and weight of your garage doors determine the length of the torsion spring as well as how many springs you will need.
