Aircraft-grade lifting cables.
When a 1/8" galvanized steel cable snaps under tension, the door drops instantly. We install heavy-duty, 7x19 strand cables for maximum tensile strength.
The Anatomy of a Cable Failure
Lifting cables operate on an aluminum drum. Over time, moisture from the Central Coast marine layer causes rust and fraying. Once a single strand breaks, the integrity of the entire cable is compromised. We highly recommend replacing both cables simultaneously to maintain balance.
Warning Signs
- Fraying or unspooled wire
- Door hangs unevenly
- Slacking cables when open
- Grinding noises from the drum
Cable Replacement FAQ
No. Attempting to lift a 300lb door with a broken cable puts immense stress on the remaining cable and the tracks, often leading to a catastrophic collapse. Leave it alone and call a professional immediately.
With our fully stocked trucks, we typically complete a dual cable replacement and system recalibration in under 60 minutes.
