Torsion springs
Torsion springs come in a wide variety of sizes and are considered safer than extension springs. They have a unique mechanism and are more reliable. Torsion springs are mounted horizontally above the opening when you pull the door down cables attached to the bottom force the springs to wind up. When you open the door, springs unwind, transferring the energy to the door, lifting it and opening it easily. These springs last for more than 5-7 years and if properly maintained can even last for more than that.
