One Spring vs. Two Garage Door Springs

What is a garage door spring and where do I look for it?  It is that object that is located above the garage door that looks like a coil or spring.  The proper name used in the garage door industry is called a torsion spring.

A torsion spring is a spring that works by torsion or twisting; that is a flexible object that stores mechanical energy when it is twisted. When it is twisted, it exerts a force (actually torque) in the opposite direction, proportional to the amount (angle) it is twisted.

So why would it be important to have one or two garage door springs on a standard two car garage door? Read More→
