Specifications

Designed for 7' High Garage Doors

This 25-42 extension spring is designed for compatible sectional garage doors measuring approximately 7 feet high.

The 25-42 designation identifies the spring's approximate:

• 25" spring length

• 42" stretch specification

Correct extension spring selection is essential for maintaining proper garage door balance and safe operation.

170 lb Spring Rating

This spring is rated for a 170 lb garage door application.

The spring rating should match the actual weight and configuration of the garage door. Installing an incorrectly rated spring can cause:

• Poor door balance

• Excessive opener strain

• Uneven lifting

• Premature hardware wear

• Difficulty opening or closing

• Unsafe door movement

Always verify the required spring rating before ordering.

Orange Color Code

The Orange color code identifies a 170 lb extension spring in the 25-42 series.

Because extension spring colors repeat as weight ratings increase, do not order based on color alone.

Confirm all of the following:

• 7' door height

• 25-42 spring series

• 170 lb rating

• Orange color code

• End configuration

Clips Included

This spring includes the appropriate clips for compatible installation applications.

Always compare the existing spring and hardware before replacement, including:

• Spring ends

• Clips

• Pulleys

• Lift cables

• Safety cables

• Rear track supports

• Spring attachment points

How Extension Springs Work

Extension springs are typically installed alongside the horizontal garage door tracks.

As the garage door closes, the springs stretch and store mechanical energy. When the door opens, that stored energy helps counterbalance the weight of the door.

A properly matched extension spring system helps provide:

• Smooth door movement

• Proper door balance

• Reduced load on the opener

• Controlled opening and closing

• Reduced strain on cables and pulleys

Compatibility & Fitment

Designed for compatible:

• 7' high sectional garage doors

• 25-42 extension spring systems

• 170 lb spring applications

• Compatible clipped-end extension spring hardware

• Standard extension spring pulley and cable systems

This spring is not intended for torsion spring systems.

Before ordering, verify the existing spring's:

• Door height

• Weight rating

• Spring length

• Stretch specification

• Color code

• End style

Replace Extension Springs in Pairs

If your garage door uses two extension springs, replacing both springs at the same time is strongly recommended.

Springs installed together normally experience the same number of operating cycles. If one spring has broken or weakened, the opposite spring may also be approaching the end of its service life.

Installing one new spring alongside a heavily worn spring can create uneven lifting force and poor door balance.

Safety Cables

Extension springs operate under substantial tension when the garage door is closed.

Properly installed extension spring safety cables should be used where required. A safety cable runs through the spring and helps contain it if the spring breaks during operation.

Never operate an extension-spring garage door with missing, damaged, or improperly installed required safety hardware.

Safety Warning

⚠️ Garage door extension springs store significant mechanical energy and can cause serious injury, death, or property damage if improperly installed or handled.

Installation and replacement should be performed by a qualified person familiar with extension spring systems, lift cables, pulleys, and safety cables.

Never disconnect or remove a stretched extension spring without first safely releasing spring tension.
