At Christian Doors, your safety and the reliable operation of your garage door are our top concerns, which is why we want to highlight the vital role of garage door cables. These heavy-duty steel cables work in tandem with the springs to lift and lower the door smoothly, bearing immense tension to counterbalance the door’s weight—often hundreds of pounds. Whether you have a torsion spring system (cables running along the sides and attached to drums above) or extension springs, the cables are under constant high stress with every use, making them prone to wear over time.
A broken garage door cable is extremely dangerous and can happen suddenly, causing the door to crash down uncontrollably, potentially leading to severe injury, vehicle damage, or even structural harm to your garage. Signs of impending failure include fraying strands, rust, uneven door movement, slack in the cables when the door is open, or strange noises during operation. Never attempt to open or close a door with a suspected broken cable, as the sudden release of tension can whip the cable violently.
To inspect your cables safely, visually check them monthly with the door fully closed (tension relieved): look for frayed or broken strands, rust spots, or any separation from the drums or bottom brackets. Do not touch or adjust them yourself due to the high risk involved. If you notice any issues, stop using the door immediately and call Christian Doors for professional inspection and replacement—we have the expertise and tools to handle these repairs safely and efficiently.
