Extension springs are made for a specific height and weight of a garage door. The springs run along side the horizontal track, as they stress and compress they raise and lower the garage door.

Understanding the Numbers

Let’s say you’re looking at a 27 x 48 extension spring for an 8 foot garage door. It has a 27-inch relaxed or compressed length and a 48-inch stretched length, which is how far the spring should be stretched when the garage door is closed.

As you might expect, longer springs tend to be used on taller garage doors. If you use an extension spring with a different first number than the old one, you will need to adjust the cable length to achieve the necessary 10 percent of stretch when your door is open.

Don’t ever use a seven-foot extension spring for an eight-foot garage door. This forces the spring to stretch farther to allow the door to close, which creates extra tension, affects how the door is lifted and will greatly shorten the life of the spring.

Extension Springs – Weight Capacity

Garage door extension springs are manufactured to lift specific amounts of weight. Therefore each individual garage door will have a specific spring that works for it. If you have a 100 pound garage door then you will need two 100 pound springs. This is because the pulleys in the system reduce the weight that the springs can pull, so a 100 pound spring can only pull 50 pounds.

This is why two 100-pound extension springs are needed to lift a 100-pound garage door. Also, be sure to replace both extension springs at the same time in order to maintain the garage doors balance in COOS county, NH.

Garage Door Extension Spring Color Coding

Extension springs are manufactured for a specific weight and door height. They are color coded to easily determine one spring from another. Once you determine the weight of your door, you can watch our educational How To video to learn how to measure for the correct spring. After that you’ll be ready to purchase your new spring.

  • Brown: 160 pounds
  • Orange: 170 pounds
