How To Tighten Garage Door Cables
Garage door cables ensure smooth door operation, working with torsion or extension springs for balance. Over time, cables may loosen due to wear, improper installation, or spring tension issues, leading to operational problems. Before tightening cables, take safety precautions—disconnect power, wear protective gear, and secure the door.
To tighten cables, inspect for damage, determine the garage door system type, loosen the cable drum screws (for torsion spring systems), adjust the cable tension, and re-tighten the screws. Check both sides for even tension and test door movement manually and via the opener. If cables are severely damaged, misalignment persists, or the door has high-tension springs, seek professional help.
Regular maintenance, including inspections, lubrication, and spring tension checks, prevents cable slack and extends the system’s lifespan. Properly tightened cables ensure safe and efficient garage door operation.
