The Differences Between Extension and Torsion Springs in Garage Doors

Garage doors are an essential part of many homes and buildings, providing security and
convenience for accessing the space. Two types of springs are commonly used in garage
doors: extension springs and torsion springs. While both types of springs serve the same basic
purpose of counterbalancing the weight of the door, they have some significant differences that
can affect the performance and durability of the garage door system.

The Differences Between Extension and Torsion Springs in Garage Doors

Extension Springs

Extension springs are typically installed on either side of the garage door, running parallel to the
door track. As the name suggests, these springs extend and contract as the door moves up and
down. Extension springs are generally less expensive and easier to install than torsion springs,
which makes them a popular choice for many homeowners.

Torsion Springs

Torsion springs, on the other hand, are mounted above the garage door, typically on a bar or
shaft that runs parallel to the door’s tracks. These springs use torque, or twisting force, to
counterbalance the weight of the door. Torsion springs are generally more powerful and durable
than extension springs, which makes them a better choice for heavier doors or for doors that are
opened and closed frequently.

Installation and Adjustment

One major difference between extension and torsion springs is the way they are installed and
adjusted. Extension springs are relatively simple to install and can be adjusted by adding or
removing coils to increase or decrease the tension. Torsion springs, on the other hand, require
specialized tools and expertise to install and adjust, which can make them more difficult and
costly to replace.

Safety

Another important difference between these two types of springs is the safety factor. Extension
springs are typically not as safe as torsion springs because they are under a lot of tension and
can break suddenly, releasing that tension and potentially causing injury or damage. Torsion
springs, on the other hand, are designed to be safer because they use torque to counterbalance
the weight of the door, which reduces the risk of sudden failure.

Conclusion

In conclusion, while both extension and torsion springs serve the same basic purpose of
counterbalancing the weight of a garage door, they have some significant differences that can
affect the performance and safety of the garage door system. Extension springs are generally
less expensive and easier to install, but they are not as safe or durable as torsion springs.
Torsion springs are more powerful and durable, but they are also more difficult and costly to
install and adjust. Ultimately, the type of spring that is best for your garage door system will
depend on your specific needs and budget.
