Frayed, loose, or snapped lift cables cause garage doors to lift crookedly or jam midway. United Garage Door Expert provides precision cable replacement and drum re-spooling.
While counterbalance springs provide the lifting force, heavy-duty galvanized steel lift cables transfer that torque directly to the bottom brackets of your garage door. Wound tightly around aluminum cable drums on either side of the torsion shaft, these cables bear the full physical weight of the moving door on every upward and downward cycle.
Over thousands of cycles, continuous friction, moisture, and drum rubbing can cause individual steel cable strands to fray, rust, or separate, ultimately leading to sudden cable snapping.
Inspect your door cables visually (without touching high-tension parts) for these warning signals:
When replacing damaged cables, our technicians install premium 7×19 aircraft-grade galvanized steel cables with superior flexibility and fatigue resistance. We reset both cable drums, ensure exact equal length and spool tension on both sides, and inspect bottom bracket anchor pins to ensure balanced, smooth glide.
Cables usually slip off the drum when the door encounters an obstruction while closing, when spring tension becomes unbalanced, or if a roller jams tightly in the track.
No. The bottom cable bracket is under extreme tension from the counterbalance spring. Loosening or adjusting this bracket without neutralizing spring tension can cause severe injury.
Yes. Both cables undergo identical cycle wear. Replacing both ensures equal length, balanced tension, and prevents the second older cable from snapping shortly after.
