Short answer: The two main garage door spring types work differently and fail differently. Here's how to tell them apart.
The two main garage door spring types work differently and fail differently. Here's how to tell them apart.
Torsion Springs
Torsion springs mount on a metal shaft above the door opening and store energy by twisting as the door closes. They tend to last longer, operate more smoothly, and are common on heavier doors. Because they hold high tension, they should only be adjusted by a trained technician.
Extension Springs
Extension springs run along the horizontal tracks on either side of the door and stretch to counterbalance its weight. They are common on lighter, older doors. A safety cable running through each spring is important, because it contains the spring if it breaks.
Why It Matters
Knowing your spring type helps you understand replacement costs and safety needs. Whichever type you have, a broken spring makes the door far too heavy to lift safely by hand.
