Floating Torsion Spring Tension Adjustment System
An overhead door having a floating spring adjustment is presented. Tension is applied to a torsion spring while the door is in the open, minimal tension state. A spring tension adjustment assembly allows the torsion spring to change in length as the number of coils shrink and grow through door operation thereby eliminating the “snake-like” or serpentine appearance from an improper fixed torsion spring length.
