WHY CABLES COME OFF DRUMS
A slipped cable is usually a symptom—not the whole problem.
Loss of tension, uneven door travel, a damaged drum, or related hardware trouble can change the cable path. The cable may cross the drum grooves, go slack, or slip free, leaving the door crooked or wedged in the tracks.
- Lift cable
- Condition, length, routing, and attachment all affect how it performs.
- Cable drum
- The cable should wind cleanly in the grooves without crossing or rubbing.
- Bottom attachment
- The cable connects at a fixture that can remain under spring tension.
