Cable drums sit at either end of the torsion pole and the lifting cables wind into their grooves. Matched drums are what keep both sides of the door rising at the same rate.
| Variant | Specification |
|---|---|
| Double | For double width doors |
| Caravan | For caravan height doors |
Drums are handed and are replaced as a pair. A worn drum will chew through a new cable, so both get checked together.
Our technicians carry spares on the vehicle and work on every make of door, not only our own. Book a callout at your nearest branch.
