How Many Turns On A 12 Ft Garage Door Spring

Types of Garage Door Springs

Before we delve into the number of turns needed for a 12 ft garage door spring, it’s crucial to understand that there are two primary types of garage door springs: torsion springs and extension springs. Torsion springs are located above the door, while extension springs are situated on either side of the door.

Torsion Springs and the 12 Ft Garage Door

Torsion springs are commonly used for heavier garage doors, such as those that are 12 feet in width. These springs are wound tightly to store energy, which is then released to lift the door. To determine the number of turns needed for a 12 ft garage door spring, follow these steps:

  1. Measure the Spring Length: Start by measuring the length of the torsion spring. You’ll need this measurement to ensure you wind it correctly.
  2. Determine the Spring Size: The size of the spring (usually in terms of wire gauge) will impact the number of turns required. Thicker springs will need fewer turns.
  3. Calculate the Number of Turns: Manufacturers offer turn guidelines based on spring size and door height. As a rough rule, for a 12 ft door, plan on 3 to 4 turns. For precision, consult the manufacturer or a professional.

Seeking Professional Assistance

While you can estimate the turns for a 12 ft garage door spring, it’s vital to emphasize the extreme danger of working with them. These springs are wound tightly and store a significant amount of energy. Any errors in adjustment can result in injuries or property damage.
