Understanding Your Garage Door Cables

Your garage door is one of the hardest-working components of your home, and at its core are the garage door cables. These cables play a vital role in ensuring your garage door operates smoothly and safely every day. But what happens when they wear out or break? Knowing more about garage door cables can help you identify potential issues before they turn into costly problems.
This blog will take you through the ins and outs of garage door cables, including their types, warning signs, safety tips, and when to call a professional.

Different Types of Garage Door Cables

Torsion Cables
Torsion cables are used with torsion spring systems and are located on both sides of the garage door. These cables support the heavy weight of the door, working in tandem with the spring to lift and lower the door safely. Due to the immense tension they are under, torsion cables are durable but require regular checks to prevent accidents caused by wear or snapping.

Extension Cables
Extension cables, on the other hand, are part of extension spring systems and run alongside the tracks of the garage door. These cables stretch and contract to balance the door’s weight. While they aren’t under as much tension as torsion cables, they are still subject to wear and need to be monitored for fraying or breakage.

How to Identify the Right Cable for Your Door
Choosing the right cable for your garage door depends on two major factors—your door’s weight and the type of spring system it uses. For instance, many heavier garage doors utilize torsion cables because of their strength and stability. Lighter doors may rely on extension cables. Check with your garage door’s specifications or consult a professional to ensure you’re using the correct cable for optimal performance.

Signs of Wear and Tear
Recognizing the signs of cable wear early can save you both time and money. Look for issues like:
Fraying or visible deterioration along the cable.
Rusted or corroded spots.
Slack or loose cables that don’t appear to have proper tension.
The garage door moving unevenly or making unusual noises during operation.
If you notice any of these warning signs, it’s time for an inspection or replacement.

Safety First: Working with Garage Door

Cables are under extreme tension, and mishandling them can lead to severe injuries. That’s why safety should always come first when dealing with garage door cables.
Tools You Might Need
If you’re considering inspecting your cables yourself, make sure you have essential tools like:
Safety gloves and goggles.
A sturdy ladder.
Locking pliers or C-clamps.
Wrenches or socket sets.
However, even with the right tools, it is strongly recommended to call a professional if you’re not confident about handling cables under tension.

When to Call a Professional

There are situations where DIY simply isn’t worth the risk. For instance:
If you’re dealing with broken torsion cables.
Your door weighs too much to handle without proper equipment.
You’re unsure how to adjust tension safely.
Professionals not only bring expertise but also specialized tools to get the job done safely and efficiently. Hiring someone qualified ensures long-term reliability and peace of mind.
