A commercial customer had called us to repair the cables on his large garage door in a mechanic shop. Upon arrival we saw that the cables had frayed and would have broken soon. We removed the tension from each torsion spring and loosened the cables enough to remove them. Placing the garage door on blocks of wood makes it easier to remove the bottom brackets so you can remove the cables easier. In this situation the old cables were different lengths, most likely the previous garage door company replaced only one cable instead of both, so the torsion springs had to be released from the torsion bar in order to adjust the center coupling and balance the garage door.
