Garage Door Extension Springs
Open Looped End
Double Looped End
Extension springs are based on resistance. They are tightly coiled springs that increase resistance as more force is used to pull it out, thereby extending the spring. The general purpose of extension springs is to return moving objects back to their starting positions. The object moves, extending the spring, and the resistance of the extension spring takes effect, pulling it back. This is exactly how garage door extension springs function.
Of course, not all garage door extension springs or overhead door extension springs are alike. Even the hook or loop at the end of the spring, which one uses to mount the spring, may be a different style or shape depending on the needs or shape of the particular object you are hooking the extension spring to.
Garage door extension springs are designed specifically for a garage door’s height and weight. A seven-foot door will not use the same spring as an eight-foot door. Extension springs operate on a pulley system and are placed above the horizontal track of the garage door. The initial tension of the extension springs may vary. The initial tension is the force that holds the coil together and must be exceeded to get the extension spring working. Although the standard initial tension is appropriate for most garage door extension spring needs, initial tension can be customized for specific situations.
