Confirm Before Ordering:
Do not select by color alone. Verify the garage door’s actual dead weight, height, existing spring length, end style, maximum stretch, pulley configuration, and spring quantity.
Replace Both Springs:
Extension springs should be replaced as a pair to maintain balanced lifting force. Safety containment cables should also be installed and inspected on both sides of the door.
Safety:
Garage door extension springs and lift cables operate under high tension. Secure the door, disconnect the opener, and fully release spring tension before service. Follow the door manufacturer’s instructions or use a qualified garage door technician.
