Install the torsion spring system above the garage door opening. This system consists of a metal shaft, one or more torsion springs, and cables that attach to the bottom of the door. The springs are critical for counterbalancing the door's weight. Once installed, the springs must be precisely tensioned using winding bars. The video specifies 8.75 turns for this particular door, which weighs approximately 450 pounds. Each turn adds significant torque. After reaching the correct tension, the set screws are tightened to hold the springs in place. This step is extremely dangerous and requires specialized tools and expertise; improper tensioning can lead to severe injury.
