Specifications

27-48 Series for 8' High Doors

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

The 27-48 designation identifies the spring series and should not be treated as a literal 27" × 48" physical measurement.

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

• Door height

• Spring series

• Required pull rating

• End configuration

• Existing spring setup

• Actual door counterbalance requirements

260 lb Pull Rating

This spring provides a 260 lb pull rating and is designed for heavier sectional garage door applications requiring this specific counterbalance capacity.

Using an incorrectly rated spring can cause:

• Heavy manual 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.

Brown Color Code

The Brown identification color corresponds to the 260 lb extension-spring rating.

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

Before ordering, confirm:

• 8' door application

• 27-48 Series

• 260 lb pull rating

• Brown identification

• Clipped-end configuration

Clipped Ends – Clips Included

This version features a clipped-end configuration and includes the clips required for compatible installation.

This differs from lower-rated 27-48 springs that may use double-loop ends.

Compare your existing spring and attachment hardware before ordering to confirm the replacement configuration matches your door.

Heavy-Duty Extension Spring Application

A 260 lb extension spring is intended for substantially heavier applications than common light-duty residential extension springs.

Correct spring selection depends on the actual garage door weight and counterbalance requirements.

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

How Extension Springs Work

Extension springs are normally 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

• 260 lb pull rating

• Brown 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 result in:

• Uneven lifting force

• Unequal cable tension

• Crooked door movement

• 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 it 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, containment cables, and proper installation procedures.
