Garage door springs act as the counter-balance system for garage doors and do most of the work in opening and closing your garage door. With the help of these springs, it only requires a few pounds of force to open and close a door weighing as much as a few hundred pounds.
Garage door torsion springs are used to assist the lifting and lowering of a garage door. Depending on the size and weight of the door itself, there may be either one or two of these springs, mounted on brackets above the door. For lighter doors, only one is needed. For heavier doors, like solid steel, or wood doors, two may be attached.
