How It Works

Extension springs stretch as the garage door closes, storing mechanical energy. As the door opens, the springs contract and assist with lifting the weight of the door.

When properly selected and installed, the spring system helps keep the door balanced and reduces unnecessary strain on the garage door opener, cables, pulleys, and related hardware.

Compatibility

Designed primarily for 8-foot sectional garage doors equipped with an extension spring system.

Before ordering, verify:

• Existing spring length

• Required spring stretch

• Door height

• Door weight

• Spring color identification

• End configuration

• Existing cable and pulley system

Do not select an extension spring based only on color. Door weight and the existing spring specifications should be verified before replacement.

Important Spring Rating Information

The 380 lb rating is part of the spring specification used to properly match the extension spring to the garage door system.

On systems using one extension spring on each side of the door, both springs should be correctly matched to the door and to each other.

When both existing springs have similar age and use, replacing them as a matched pair is generally recommended.

Installation & Safety

Garage door extension springs operate under substantial tension and can cause serious injury, property damage, or death if incorrectly selected, handled, installed, or removed.

Extension spring systems also rely on cables, pulleys, brackets, and other hardware that must be correctly installed and in safe operating condition.

Installation should be performed by a qualified garage door professional familiar with extension spring systems.

Always verify the door weight, spring specifications, attachment method, cables, pulleys, and related hardware before installation.
