How Many Turns on a Double Spring Garage Door?

Garage door springs are an essential part of any garage door. They provide the necessary force to lift and lower the door, making it easy for homeowners to access their vehicles. There are two main types of garage door springs: extension springs and torsion springs. Extension springs are the most common type of garage door spring. Torsion springs are located at the top of the garage door and are less common.

Torsion springs are typically wound with a specific number of turns. The number of turns on a torsion spring depends on the size of the spring and the weight of the garage door. The exact number of turns on a double spring garage door will vary depending on the manufacturer and the specific spring that is used. However, in general, double spring garage doors typically have 30-36 turns.

How to determine the number of turns on a torsion spring

The number of turns on a torsion spring can be determined by counting the number of times the spring winds around its axis. To do this, you will need to remove the spring from the garage door.

To remove a torsion spring, follow these steps:

  1. Disengage the garage door opener. This can be done by pulling the emergency release cord or handle.
  2. Remove the garage door balance bolts. These bolts are located on each side of the garage door track.
  3. Use a wrench or socket wrench to loosen the set screws on each end of the spring.
  4. Carefully remove the spring from the garage door.

Once the spring is removed, you can count the number of times it winds around its axis. The number of turns will be visible on the outside of the spring.

What happens if you add or remove turns on a torsion spring?

Adding or removing turns on a torsion spring can affect the force of the spring. If you add turns, the spring will be stronger. If you remove turns, the spring will be weaker.

Changing the number of turns on a torsion spring should only be done by a qualified professional. If you are not comfortable working with torsion springs, you should call a professional to adjust the spring for you.

Additional information

  • Torsion springs are typically made of galvanized steel.
  • Torsion springs can last for many years if they are properly maintained.
  • If a torsion spring breaks, it is important to replace it as soon as possible. A broken spring can be a safety hazard.

Additional details

The size of the torsion spring is measured by the diameter of the wire and the number of coils. The weight of the garage door is also a factor in determining the number of turns on the spring.

For example, a double spring garage door with a 1-inch diameter wire and 10 coils will have a total of 20 turns. If the garage door weighs 200 pounds, the spring will need to be wound with an additional 2 turns to provide enough force to lift the door.

It is important to note that the number of turns on a torsion spring is not the only factor that affects the force of the spring. The quality of the spring and the condition of the spring also play a role.
