SSC 7' Garage Door Extension Spring – 140 lb – 25" x 42" – Blue – Clips Included

🇺🇸 Made in USA

This SSC garage door extension spring is designed for sectional garage doors approximately 7 feet high requiring a 140 lb spring rating.

Manufactured by Service Spring Corporation (SSC), this spring is part of the 25-42 series, measuring approximately 25" in its relaxed position and designed for approximately 42" of working stretch.

This version features clipped ends, a durable black-coated oil-tempered spring wire, and the Blue identification colorcorresponding to the 140 lb rating.

Specifications

Designed for 7' High Garage Doors

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

The spring measures approximately 25" when relaxed and stretches as the garage door closes, storing the energy needed to help counterbalance the weight of the door during opening.

140 lb Pull Rating

This spring has a 140 lb pull rating.

Correct spring rating is essential for proper door balance. A spring that is too weak or too strong can cause:

• Heavy manual operation

• Excessive opener strain

• Uneven lifting

• Improper cable tension

• Door drift

• Premature hardware wear

Always match the replacement spring to the required door weight and existing spring specifications.

Blue Color Code

The Blue color code identifies the 140 lb extension spring rating in SSC's 25-42 series.

Color coding is useful for identification, but spring selection should never be based on color alone.

Before ordering, verify:

• Door height

• Spring rating

• Relaxed length

• Working stretch

• End style

• Existing spring configuration

Clips Included

This version uses clipped ends and includes the appropriate spring clips for compatible installations.

This is different from SSC's double-loop and open-loop versions of the 25-42 spring.

If replacing an existing spring, confirm that your system uses the same clip-style attachment configuration.

How Extension Springs Work

Extension springs are normally installed along the horizontal tracks on both sides of the garage door.

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

A properly sized extension-spring system provides:

• Smooth door movement

• Proper counterbalance

• Reduced load on the opener

• Consistent cable tension

• Easier manual operation

Compatibility & Fitment

Extension springs are not universal.

This spring should be selected when the system requires:

• 7' door application

• 25-42 extension spring

• 140 lb pull rating

• Blue identification

• Clip-style ends

Also inspect the existing pulleys, cables, attachment hardware, track supports, and safety cables during spring replacement.

Replace Extension Springs in Pairs

For two-spring extension systems, replacing both springs as a matching pair is strongly recommended.

Both springs normally experience approximately the same number of operating cycles. If one fails, the opposite spring may already be significantly fatigued.

Using one new spring with one worn spring can result in:

• Uneven lifting force

• Unequal cable tension

• Crooked door travel

• Poor balance

• Increased opener and hardware wear

Safety Cables Recommended

Extension-spring systems should use properly installed safety containment cables running through the springs.

If a spring breaks, the safety cable helps prevent the spring from becoming a dangerous projectile.

Inspect existing safety cables whenever replacing extension springs and replace any damaged or missing components.

Safety Warning

⚠️ Garage door extension springs operate under substantial tension and can cause severe injury, death, or property damage if improperly handled.

Never remove an extension spring, pulley, cable, clip, or attachment point while the spring is stretched.

Secure the garage door and fully release spring tension before servicing the extension-spring system.

Installation should be performed by a qualified person familiar with garage door extension springs, containment cables, and proper safety procedures.
