Springs are made to meet the characteristics of each door in terms of its size and weight. Although there are varying types, they're all installed for the same purpose, which is to counterbalance and move the door.
When new ones are chosen, knowing the weight of the door or measuring the older ones accurately is of the essence. Average residential doors often have a pair of extension or torsion springs. A double-car door or larger/heavier types might have more. In any case, proper installation and continuous maintenance can help prevent malfunctions and keep safety at a maximum level.
Extension and torsion are the two main types. Both are coiled and store tremendous power among their coils in order to lift the heavy door. Their installation, however, has certain differences. The extension type are installed above the tracks at the two sides of the door while the torsion type are mounted above the door's opening. The coils of the extension springs are stressed when the door is shut and the door opens as the coils contract. There is a metal rod called a shaft that runs through torsion springs. They stress across it and unwinds to open the door.
