Manufactured by Service Spring Corporation (SSC), this spring measures approximately 27" in its relaxed positionand is designed for up to approximately 48" of working stretch.

The spring features double-loop ends, a durable black-coated finish, and a Light Blue DASMA identification colorcorresponding to the 90 lb pull rating.

Specifications

Designed for 8' High Garage Doors

The 27-48 extension spring series is commonly used on sectional garage doors approximately 8 feet high.

The spring is approximately 27" long when relaxed and is designed to extend to approximately 48" during normal door operation.

Always verify the existing spring specifications and actual door weight before selecting a replacement.

90 lb Pull Rating

This spring is rated for a 90 lb garage door application.

The spring rating refers to the counterbalance requirement of the door system and should not be selected solely by visually comparing the old spring.

For a typical two-spring extension system, both springs should have the correct matching rating for the door.

Light Blue DASMA Color Code

The Light Blue color code identifies the 90 lb spring rating.

Color coding helps identify replacement springs, but color alone should never be the only measurement used.

Before ordering, verify:

• Door height

• Door weight

• Relaxed spring length

• Maximum stretch

• End configuration

• Existing spring rating

• Number of springs

Double-Loop Ends

This version uses double-loop ends for attachment to compatible extension-spring hardware.

Clips are not included with this version.

If your existing system uses clipped-end springs, confirm the required spring and attachment hardware 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. When the door opens, that stored energy helps counterbalance the weight of the door.

Correct spring sizing is critical for:

• Proper door balance

• Smooth manual operation

• Reduced opener strain

• Proper cable tension

• Safe door operation

Compatibility & Fitment

Extension springs are not universal.

This spring should be used only when the garage door system requires a:

• 27-48 extension spring

• 90 lb pull rating

• 8' door application

• Double-loop end configuration

Also inspect the existing pulleys, lift cables, attachment hardware, track, and safety cables before installation.

Replace Extension Springs in Pairs

When one extension spring fails, the opposite spring has normally experienced approximately the same number of operating cycles.

For balanced operation, extension springs should generally be replaced as a matching pair.

Installing one new spring alongside an older fatigued spring can cause:

• Uneven lifting force

• Door imbalance

• Uneven cable tension

• Increased hardware wear

• Poor opener performance

Safety Cables Recommended

Every extension-spring system should use properly installed safety containment cables running through the springs.

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

Inspect existing safety cables whenever replacing extension springs and replace damaged or missing components before operating the door.

Safety Warning

⚠️ Garage door extension springs and lift cables operate under significant tension and can cause serious injury or property damage if improperly serviced.

Secure the garage door and fully release spring tension before removing or installing extension-spring components.

Do not disconnect an extension spring, pulley, cable, or attachment point while the spring is stretched.

Installation should be performed by a qualified person familiar with garage door extension-spring systems and proper safety procedures.
