Garage door extension cable

 

 

The lift cables are responsible for opening and closing the garage door, and they connect the bottom brackets to the drums that are located on the tube. The width and strength of the cables vary depending on the weight of the garage door. Additionally, safety cables are a necessary component for residential garage doors that use extension spring systems. These cables are positioned within the springs, serving as a safeguard in case the springs break and preventing any potential damage.
