Garage Door Extension Springs

Are another type of spring system used in garage doors. They are typically located on either side of the garage door and run parallel to the horizontal tracks. Unlike torsion springs, which are located above the garage door and provide tension through winding and unwinding, extension springs are stretched out and provide tension through their extension and contraction.

When the garage door is closed, the extension springs are stretched out to their full length. When the door opener is activated, the springs contract, pulling on the cables attached to the bottom corners of the door and lifting it. Extension springs are typically made of steel and are coated to prevent rust and corrosion.

Like torsion springs, extension springs are designed to last for a specific number of cycles and can be affected by improper use or lack of maintenance. It is also important to note that working with garage door extension springs can be dangerous, as they are under a lot of tension and can cause serious injury if they break or are not handled properly. It is recommended to get it done by professional.

If you're experiencing issues with your garage door or think that your extension springs might need to be replaced, it is best to contact a professional garage door technician for assistance.
