How It Works

Extension springs stretch as the garage door closes, storing mechanical energy. As the door opens, the springs contract and help lift the weight of the door.

A properly selected extension spring system helps keep the door balanced so it can move smoothly through the track and reduces unnecessary strain on the garage door opener and other hardware.

Compatibility

Designed primarily for 7-foot sectional garage doors equipped with an extension spring system.

Before ordering, verify:

• Existing spring length

• Spring stretch

• Door height

• Door weight

• Spring color identification

• End configuration

• Existing pulley and cable system

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

Important Spring Rating Information

The 300 lb rating refers to the spring specification used to match the spring to the properly configured garage door system.

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

Replacing extension springs as a matched pair is generally recommended when both springs have similar age and service history.

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 use cables, pulleys, brackets, and other components that must be correctly positioned 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 rating, spring dimensions, attachment method, cables, pulleys, and related hardware before installation.
