Understanding the 25/42 Measurement
The spring body measures 25 inches when relaxed and is designed for 42 inches of additional stretch. This corresponds to approximately 67 inches of extended body length, excluding end loops. The “42” identifies spring travel, not total extended length.
Compatibility and Spring Selection
Designed for sectional doors with a matching extension spring system. Confirm door weight, door height, spring length, stretch, and end configuration before ordering.
In a standard two-spring residential setup, two matching 150 lb-rated springs are selected for a 150 lb door—not a 300 lb door. Red identification paint alone does not establish compatibility because spring colors repeat across weight ratings.
This open-loop model is not a clipped-end spring. Verify that the end configuration matches the door’s attachment hardware.
Replacement Recommendations
Replace both springs together to maintain balanced operation and avoid pairing a new spring with a fatigued spring. Have the lift cables, pulleys, mounting hardware, and safety containment cables inspected during replacement.
Safety Warning
Garage door extension springs store substantial energy and can cause serious injury or property damage if handled incorrectly. Installation and replacement should be performed by a qualified garage door technician.
Use properly installed safety containment cables through both extension springs. Never disconnect springs, cables, pulleys, or attachment hardware while under tension. Do not operate a door with a broken spring or damaged cable.
