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

Compatibility

Designed primarily for 8-foot sectional garage doors equipped with a compatible extension spring counterbalance system.

Before ordering, verify:

• Existing spring specifications

• Door height

• Door weight

• Spring length and stretch requirements

• Spring color identification

• End configuration

• Cable and pulley arrangement

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

Important Spring Selection Information

Extension springs must be correctly sized for the garage door they are supporting.

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.
