Designed for 7' High Garage Doors
The 25-42 extension spring series is designed for compatible sectional garage doors approximately 7 feet high.
As the door closes, the spring stretches and stores mechanical energy. As the door opens, that stored energy helps counterbalance the weight of the door.
Correct spring sizing is essential for smooth and properly balanced operation.
120 lb Pull Rating
This spring has a 120 lb pull rating.
Do not select an extension spring based only on its physical size or appearance. Springs that look similar can provide significantly different lifting force.
An incorrectly rated spring may cause:
-
A door that feels too heavy
-
A door that rises by itself
-
Uneven door movement
-
Improper cable tension
-
Excessive garage door opener strain
-
Premature pulley and hardware wear
Green Color Code
The Green identification color corresponds to the 120 lb extension spring rating.
Color coding makes spring identification easier, but always verify the complete spring specifications before ordering.
Confirm:
-
Door height
-
Door weight
-
Spring rating
-
Relaxed spring length
-
Working stretch
-
End configuration
Double-Loop Ends
This spring features durable double-loop ends for attachment to compatible extension-spring hardware.
Clips are not included with this version.
SSC also manufactures open-loop and clipped-end versions, so compare your existing spring attachment style before ordering.
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 energy. During opening, this stored energy helps lift and counterbalance the door.
A properly sized extension-spring system helps provide:
-
Smooth door travel
-
Proper counterbalance
-
Reduced opener load
-
Consistent cable tension
-
Easier manual operation
Compatibility & Fitment
Extension springs are not universal.
This spring should be selected when your garage door system requires:
-
7' high door
-
25-42 spring configuration
-
120 lb pull rating
-
Green identification
-
Double-loop ends
Also inspect the existing pulleys, lift cables, attachment hardware, track supports, and safety cables whenever replacing extension springs.
Replace Extension Springs in Pairs
For doors using two extension springs, replacing both springs as a matching pair is generally recommended.
Both springs normally experience approximately the same number of cycles. If one spring breaks or weakens, the opposite spring may already be fatigued.
Using one new spring with one worn spring can cause:
-
Uneven lifting force
-
Unequal cable tension
-
Crooked door travel
-
Poor balance
-
Increased hardware wear
Safety Cables Strongly Recommended
Extension-spring systems should use properly installed safety containment cables running through each spring.
If a spring breaks, the safety cable helps contain it and reduces the risk of the spring becoming a dangerous projectile.
Inspect existing safety cables whenever replacing extension springs.

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, lift cable, 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, safety containment cables, and proper installation procedures.
