Installation Notes

Garage door pulley and cable work should be performed by a qualified garage door technician. Always disengage the garage door opener and release spring tension safely before servicing cable or pulley hardware. Torsion and extension spring systems store significant mechanical energy and require proper tools and training to service safely. Follow all applicable local codes and manufacturer guidelines when replacing cable system components.
