What are Garage Door Cables?

Garage door cables are essential components of your garage door mechanism.

They work in tandem with springs and tracks to facilitate the smooth lifting and lowering of the door.

These high-tension cables are designed to withstand significant stress.

They play a crucial role in balancing the weight of the door.

Over time, cables can experience wear and tear.

This can lead to fraying, loss of tension, or even complete failure.

Regular maintenance and timely replacement of these cables are vital.

Neglecting cable maintenance can result in an unbalanced door.

It may also cause the door to fall off its tracks, posing serious risks to people and property.

Understanding Cable Function

Garage door cables are typically made of galvanized steel for durability and strength.

They’re designed to handle the weight of the door and the tension from the springs.

When you open your garage door, the cables help lift the weight by unwinding from drums located above the door.

As the door closes, the cables wind back onto the drums, controlling the descent of the door.

This system ensures smooth operation and prevents the door from slamming shut.

The cables also help distribute the weight evenly across the door.

This reduces stress on other components.

Types of Garage Door Cables

There are two main types of garage door cables:

1. Lifting cables: These are the primary cables that connect the bottom of the door to the cable drums.
2. Safety cables: Found on extension spring systems, these run through the springs to prevent injury if a spring breaks.

Knowing which type of cable your garage door uses is important for maintenance and replacement.

Signs that Your Garage Door Cable Needs Replacing

Identifying the need for cable replacement early can prevent more serious issues.

It also ensures the continued safe operation of your garage door.

Here are some key indicators that your garage door cable may need replacing:
