A torsion spring counterbalance system consists of one or two tightly wound up springs on a steel shaft with cable drums at both ends. The entire apparatus mounts on the header wall above the garage door and has three supports: a center bearing plate with a steel or nylon bearing and two end bearing plates at both ends. The springs themselves consist of the steel wire with a stationary cone at one end and a winding cone at the other end. The stationary cone is attached to the center bearing plate. The winding cone consists of holes every 90 degrees for winding the springs and two set screws to secure the springs to the shaft. Steel counterbalance cables run from the roller brackets at the bottom corners of the door to a notch in the cable drums. When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension.[7]
The lightweight design also causes a decrease in the insulation of these doors, so individuals that live in colder climates may want to consider other options for their garage door needs.  Fiberglass does not corrode when subjected to salt-water like some other door styles out there.  Individuals that live in coastal areas will find this feature beneficial for their needs.
Jerrod the technician had answers to all my questions. He was very knowledgeable and very patiently explained what was going on with my garage door and the opener. I would definitely recommend A1 garage door service to friends and family. I was given options to either repair the door or replace it.
