SELECTION GUIDE
SELECTION GUIDE
The most reliable way to pick the right spring is based on
the color of your current springs or the weight of the door.
You can weigh your door using a standard home scale, but the springs must
be disconnected. 2 people are suggested, and always exercise caution.
Before purchasing a replacement garage door spring, ensure
you have identified the correct springs for your garage door.
