⚠️
High-Tension Hardware Safety Notice: Garage door counterbalance systems (including torsion springs, extension springs, lift cables, bottom corner brackets, and center bearing plates) operate under intense mechanical tension capable of causing serious injury. Homeowners should never attempt to unbolt, adjust, or replace these components without proper tools and training.
