Specifications

27-48 Series for 8' High Doors

This spring is part of SSC's 27-48 Series, designed for compatible 8-foot-high sectional garage doors.

The 27-48 designation identifies the spring series and should not be treated as a literal 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

• Door counterbalance requirements

220 lb Pull Rating

This spring provides a 220 lb pull rating.

Correct spring strength is essential for proper garage door balance. Installing a spring with too little or too much lifting force can result in:

• Heavy manual operation

• A door that rises unexpectedly

• Uneven lifting

• Incorrect cable tension

• Excessive opener strain

• Premature pulley and hardware wear

Always verify the required spring rating before ordering.

Green Color Code

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

Extension-spring colors repeat at different weight ranges, so color alone should never determine the correct replacement spring.

Confirm:

• 8' door application

• 27-48 Series

• 220 lb pull rating

• Green identification

• Clipped-end configuration

Clipped Ends – Clips Included

This version features clipped ends and includes the required clips for compatible extension-spring installations.

SSC uses clipped-end configurations on the heavier end of this series, rather than the double-loop ends used on many lower-rated 27-48 springs.

Compare your existing spring and attachment hardware before ordering.

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 stretch 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 garage door 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:

• 8' high garage door

• 27-48 Series

• 220 lb pull rating

• Green color code

• Clipped ends with clips

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 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, 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.
