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 extension spring system helps keep the door balanced and reduces unnecessary strain on the opener, cables, pulleys, rollers, and related hardware.

Compatibility

Designed primarily for 7-foot sectional garage doors equipped with a compatible extension spring counterbalance system.

Before ordering, verify:

• Existing spring length

• Required spring stretch

• Door height

• Door weight

• Spring color identification

• End configuration

• Cable and pulley arrangement

Do not select an extension spring based only on color. The spring must be correctly matched to the weight and configuration of the door.

Important Spring Rating Information

The 330 lb rating is part of the spring specification used to properly match the spring to the garage door counterbalance system.

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

If both existing springs have similar age and service history, 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 improperly selected, handled, installed, or removed.

Extension spring systems rely on springs, cables, pulleys, brackets, safety cables, and related hardware that must all be correctly installed and maintained.

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.
