Specifications

25-42 Series for 7' High Doors

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

The 25-42 designation identifies this SSC extension-spring family. Correct spring selection should be based on the complete specification, including:

• Door height

• Required pull rating

• Spring series

• End configuration

• Existing spring configuration

• Door counterbalance requirements

110 lb Pull Rating

This spring provides a 110 lb pull rating.

Correct spring rating is critical for proper garage door balance. A spring with too little or too much lifting force can result in:

• A door that feels excessively heavy

• A door that rises unexpectedly

• Uneven door travel

• Improper cable tension

• Excessive opener strain

• Premature pulley and hardware wear

Always match the replacement spring to the door's required counterbalance specification.

White Color Code

The White identification color corresponds to the 110 lb rating for this SSC extension spring.

Color coding helps identify an existing spring, but do not select a replacement by color alone.

Confirm:

• 7' door application

• 25-42 Series

• 110 lb pull rating

• White identification

• Double-loop ends

Double-Loop Ends

This spring features double-loop ends designed for attachment to compatible extension-spring hardware.

Clips are not included with this version.

SSC also offers open-loop and clipped-end configurations, so compare the attachment style of your existing spring before ordering.

How Extension Springs Work

Extension springs are normally mounted alongside the horizontal tracks on both sides of a sectional garage door.

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

A properly matched extension-spring system helps provide:

• Smooth door movement

• Proper counterbalance

• Reduced garage door opener load

• Consistent cable tension

• Easier manual operation

Compatibility & Fitment

Extension springs are not universal.

This spring should be selected when your system requires:

• 7' high garage door

• 25-42 Series

• 110 lb pull rating

• White color code

• Double-loop ends

Also inspect the existing:

• Lift cables

• Pulleys

• Safety cables

• Track hardware

• Rear spring attachment points

• Fasteners and supports

Replace worn or damaged components before returning the door to service.

Replace Extension Springs in Pairs

For garage doors using two extension springs, replacing both springs as a matching pair is generally recommended.

Both springs normally experience approximately the same number of operating cycles. If one spring fails or becomes weak, 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 door balance

• Increased hardware wear

Safety Cables Strongly Recommended

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

If an extension spring breaks, the safety cable helps contain the spring and reduces the risk of it 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.
