Springs in a spring-loaded garage door system act as a
counterweight for the door. Instead of having a large
stack of weights, the tension, or "pull," of the springs
works against gravity to minimize the weight of the garage door.
This way when you lift the garage door from a closed position,
you are exerting only a fraction of the energy normally needed
to lift the garage door.
After about 10,000 cycles, springs may start to fail.
These springs usually come in pairs and when one breaks,
the second remains under tension. People have been seriously
injured when tightening or releasing the springs themselves.
That's why you need the professionals at Home Of Garage Door
who know how to safely complete garage door repairs.
How to properly measure your garage door torsion spring:
Step 1: Measure overall length of the spring--UNWOUND. Measure spring only.
Do not include the winding and stationary ends.
Step 2: Measure the Inside Diameter of the spring. It will be one of the following: 1 3/4" or 2" or 2 1/4"
Step 3 (Determine Wire Size): Measure the length of 10 coils of the spring.
Refer to Wire Chart below. Example: 10 coils measures 2 1/4" = .225 wire size.
Step 4 (Determine Spring Wind): Standing inside the garage, looking at the spring. If the spring is mounted
in the center and points to the left, the spring is Right
Hand Wound. If the spring points to
the right, it is Left Hand Wound.
