Torsion springs
Extension springs are the thing of the past which has now been replaced by new-age torsion springs, an important part of a garage door. The latter has a complex mechanism but it is also far more reliable than its previous counterpart. The torsion springs have been designed intuitively, using the equal distribution of weight technique that transfers evenly through cables that are linked with drums at its both ends. To allow the weight to spread uniformly, it is wrapped with a spring tightly over a shaft. As a result, the door is able to hold the weight more firmly and there is less instance of damage when the spring breaks suddenly.
