How Do Garage Door Springs Work?

Garage door springs supply the upward force needed to allow your opener to lift your garage door. Even a standard two car door could weigh nearly 200lbs. Without a system to counterbalance this weight, your automatic opener would need to be the size of, basically, a jet engine! The spring system delivers torque by way of tension. When the garage door is closed, the springs are wound to maximum tension. As your garage door rises, the springs naturally want to unwind. This unwinding pressure turns a tube that is attached by wires to your garage door. This torque turns the tube and helps lift the garage door.
