The purpose of extension springs, as their name implies, is to stretch or extend when there is force applied. You can find them on the sides of your garage door and fastened to the door’s swing arms. These springs get a lot of tension from thousands of stretches through the passage of years. Take note that they only have a peak functionality of 7-8 years. After that time, they might break when you least expect them to, so it is best to be proactive- change them while the 8 year period isn’t over.
Don’t ignore it because broken extension springs have so much force which can break the windshield or dent your car. Even worse is the possibility that it may accidentally hit you, your pets or children.
