Double-Looped Garage Door Extension Springs

All DURA-LIFT® garage door extension springs are manufactured with a "double loop" connection type.


Most extension springs for garage doors have a single loop that is more prone to break over the life of the spring. Two loops puts less stress on the connection point coils so they do not snap off as they age.

Looking for a Different Weight Capacity?

Listed above are the common residential sizes of garage door extension springs. If you have a need for a different weight capacity we have those too! Please contact us by clicking on the button below.

To measure the weight of your garage door, disengage the springs and place a mechanical bathroom scale under the middle of your closed door.

  1. Place door in the open position (so the springs are not under tension)

  2. Disengage the garage door opener

  3. Unhook spring from punched angle assembly

  4. Manually lift door and place scale under the middle of the door

  5. Purchase appropriate garage door extension spring weight rating



Extension springs are under extreme pressure and should only be handled by experienced personnel who have been trained in the proper procedures, tools, and safety measures. Improper use could result in serious injury or death.
