Specifications

25-42 Series for 7' High Doors

This spring is part of SSC's 25-42 Series, designed for compatible 7-foot-high sectional garage doors.

The 25-42 designation identifies the spring series and should not be treated as a simple physical measurement.

Correct replacement should be based on the complete spring specification, including:

• Door height

• Spring series

• Required pull rating

• End configuration

• Existing spring setup

• Actual door counterbalance requirements

220 lb Pull Rating

This spring provides a 220 lb pull rating and is intended for heavier sectional garage door applications requiring this specific counterbalance capacity.

Incorrect spring strength can cause:

• Heavy manual door operation

• A door that rises unexpectedly

• Poor door balance

• Uneven cable tension

• Excessive opener strain

• Premature cable, pulley, and hardware wear

Always verify the required spring rating before installation.

Green Color Code

The Green identification color corresponds to the 220 lb extension-spring rating.

Extension-spring colors repeat across different weight ranges, so Green alone does not identify the correct replacement.

Before ordering, confirm:

• 7' door application

• 25-42 Series

• 220 lb pull rating

• Green identification

• Clipped-end configuration

Clipped-End Configuration

This spring uses a clipped-end (CL) configuration for attachment to compatible garage door extension-spring hardware.

This differs from:

• Double-loop springs

• Open-loop springs

• Other extension-spring attachment configurations

Verify your existing attachment method before ordering.

Attachment clips should be confirmed separately unless specifically stated as included with the product.

Heavy-Duty Extension Spring Application

A 220 lb extension spring is intended for heavier door applications than typical lightweight residential extension springs.

Correct application depends on the actual weight and counterbalance requirements of the garage door.

Do not substitute this spring for a lighter-rated spring simply because the springs look similar.

How Extension Springs Work

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

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

A correctly matched extension-spring system helps provide:

• Smooth door travel

• Proper counterbalance

• Reduced opener strain

• Correct cable tension

• Easier manual operation

Compatibility & Fitment

Extension springs are not universal.

This spring should be selected when your system specifically requires:

• 7' high garage door

• 25-42 Series

• 220 lb pull rating

• Green color code

• Clipped-end configuration

Also inspect the existing:

• Lift cables

• Pulleys

• Safety containment cables

• Spring attachment points

• Track hardware

• Rear track supports

• Fasteners

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 weakens, the opposite spring may already be fatigued.

Using one new spring with one worn spring can result in uneven lifting force, unequal cable tension, poor door balance, and 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 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, 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, safety containment cables, and proper installation procedures.
