How to Find the Wind of a Garage Door Torsion Spring?

Look at the end of the spring to determine the wind direction. If the end of the spring points in the clockwise direction it is left-wound and if the end of the spring points in the counter-clockwise direction, it is right-wound. On most springs, wind direction is also indicated by the color of the winding cones and cable drums — red indicates a right-wound spring while black indicates a left-wound spring.
