Step-by-Step Guide: Adjusting a 16 Ft Garage Door Spring

⚠️ Safety First: Torsion springs are under high tension. Wear gloves, safety glasses, and use winding bars. If unsure, hire a professional.

Tools Needed:

• Winding bars
• Socket wrench
• Ladder
• Gloves & safety glasses

Steps:

1. Measure Door Height: Ensure the door is exactly 16 ft and fully closed.
2. Secure the Door: Lock it in place using clamps or C-clamps to prevent movement.
3. Insert Winding Bars: Into the winding cone of the spring.
4. Turn the Spring: Count the number of full rotations according to your door weight:
   • Light doors (100–150 lbs): ~30 turns
   • Heavy doors (150–200 lbs): ~34 turns
5. Check Balance: Lift the door manually. It should stay in place when halfway open.
6. Tighten Set Screws: Use a socket wrench to secure the winding cone.
7. Test the Opener: Ensure smooth opening and closing.

Tips to Maintain Your Garage Door Spring

• Lubricate Monthly: Use garage door-specific lubricant.
• Inspect Regularly: Look for wear, rust, or gaps in the spring.
• Don’t Overwind: Excess tension reduces spring life.
• Hire a Professional for Replacements: Especially for double or high-tension springs.
