APPLICATION & COMPATIBILITY
For compatible sectional garage doors with extension springs mounted alongside the horizontal tracks. Match the replacement to the door’s actual weight, spring dimensions, attachment style, and cable-and-pulley arrangement.
In a standard two-spring residential system, a matched pair of 180 lb extension springs is selected for a 180 lb door—not a 360 lb door. One spring should not be used alone to support the entire door.
The 27/48 designation means a nominal 27-inch relaxed spring length with 48 inches of additional stretch. It does not mean the fully extended spring measures 48 inches.
This spring is not a direct replacement for a 25/42 spring used on a 7-foot-high door or for a torsion spring. Color coding helps identify the weight class but does not establish compatibility by itself.
REPLACEMENT NOTES
Replacing both extension springs together helps maintain balanced lifting force and avoids pairing a new spring with a worn spring. Have the pulleys, lift cables, safety cables, and mounting hardware inspected during replacement.
This model has double-loop ends. Separate attachment clips are not listed as included.
SAFETY WARNING
Garage door springs and related hardware are under high tension. Improper installation, adjustment, or removal can cause serious injury or death. Installation and service should be performed by a trained garage door technician.
Properly installed containment safety cables must run through both extension springs. Never operate a door with a broken spring, frayed cable, damaged hardware, or uncontrolled movement.
