Garage Door Spring Tension Chart

Garage door springs are an essential part of the garage door system, as they provide the tension that raises and lowers the door. If the springs are too loose or too tight, it can affect the operation of the door and even cause damage. That's why it's important to ensure that the springs are properly tensioned.

The tension of a garage door spring is measured in pounds. The recommended tension for a garage door spring will vary depending on the size and weight of the door. For example, a standard 8-foot tall by 16-foot wide garage door will require springs with a tension of around 150 pounds per spring.

If you are not sure what the tension of your garage door springs should be, refer to the manufacturer's instructions for your door model. You can also contact a professional garage door repair company for assistance.

To tension garage door springs, you will need a spring tension gauge and a pair of spring pliers. Follow these steps to adjust the tension of the springs:

Disconnect the power to the garage door opener.
Open the garage door manually.
Locate the springs. They will be mounted on the sides of the door frame.
Attach the spring tension gauge to the spring.
Pull on the gauge until the spring is at the recommended tension.
Use the spring pliers to adjust the tension as needed.
Once the spring is at the correct tension, reconnect the power to the garage door opener and test the door's operation.

If you are not comfortable adjusting the tension of the springs yourself, it is best to contact a professional garage door repair company for assistance. Incorrectly tensioned springs can be dangerous and cause damage.
