What Are the Key Differences Between Garage Door Springs and Cables?

When it comes to garage door mechanics, two components are often talked about interchangeably; the springs and cables. While both parts play crucial roles in the safe and smooth operation of your garage door, they serve very different functions.

At Garage One, Toronto’s trusted garage door experts, we believe homeowners should understand the basics to make informed decisions about maintenance and repairs.

The Role of Garage Door Springs

Garage door springs are the muscle behind the lifting and lowering of your door. These tightly wound coils store mechanical energy and counterbalance the weight of the door, making it possible to lift it manually or with a motor.

There are two main types of springs:

  • Torsion Springs: These are mounted horizontally above the door, these springs twist to generate force.
  • Extension Springs: Located on either side of the door, these springs stretch and contract to assist movement.

Without properly functioning springs, your garage door would be extremely heavy and difficult to operate. Springs are under high tension and can be dangerous if they snap or are improperly handled, which is why professional installation and maintenance are essential. You should never try to replace your springs yourself.

The Role of Garage Door Cables

Garage door cables are engineered to work in tandem with the springs. They’re typically made of steel, running from the bottom brackets of the door up to the spring system. Their main job is to transfer the energy from the springs to lift the door evenly and safely.

Cables also work as a safety mechanism; if a spring breaks, the cables help prevent the door from crashing down suddenly, reducing the risk of injury or damage. Over time, cables can fray, rust, or snap, especially in Toronto’s fluctuating weather conditions, so regular inspection is key.

Key Differences

Here’s a quick breakdown of how these two components differ:

Springs

  • Provide the lifting force
  • Are located above or beside the door
  • Are under high tension and can be dangerous
  • Require professional service

Cables

  • Transfer the lifting force and guide movement
  • Are located along the sides of the door
  • Can snap or fray, creating a safety hazard
  • Can be visually inspected for wear

Why It Matters

Understanding the difference between springs and cables helps you recognize signs of wear and potential issues before they become costly repairs. If your garage door is making unusual noises, moving unevenly, or feels heavier than usual, that may indicate a problem with either the springs or cables or even both! Any of those signs means you should call a professional for a consultation and repair.
