Customer Problem
The homeowner noticed the lift cable on one side of their Centurion sectional door hanging loose at the bottom bracket, and the door starting to lift unevenly. On closer inspection the cable had frayed strand by strand at the anchor and finally parted — with one side unloaded the door twists in the tracks and becomes unsafe to run.
- Lift cable frayed and snapped at the bottom-bracket anchor
- Door lifting unevenly and starting to bind
- Original Centurion bottom bracket worn at the roller stem
Inspection & Diagnosis
Laid side by side, the old and new brackets told the story: the original pressed-steel bracket had worn oval where the roller stem sits and the cable anchor had chewed through the strands. The other side had the same wear, so cables and brackets were replaced as a set — the standard fix on a door of this age.
- Cable frayed through at the bracket anchor
- Bracket worn at the roller stem — replaced with a heavy-duty unit
- Opposite side showing identical wear — replaced together
- Springs, drums and tracks inspected — serviceable
Solution
With the door secured and springs de-tensioned we removed both bottom brackets, fitted new heavy-duty galvanised brackets with new rollers, ran a matched pair of new galvanised cables to the drums, and re-seated the door in the vertical tracks. Springs were re-tensioned, the door levelled and balanced, and the opener limits and safety reversal re-set.
- New heavy-duty galvanised bottom brackets both sides
- New rollers fitted with the brackets
- Matched pair of new galvanised lift cables
- Door re-seated, levelled, springs re-tensioned, opener re-set

Frequently Asked Questions
It isn't brand-specific — every sectional door anchors its cable at the bottom bracket, and that's where grit, moisture and constant flexing wear the strands. Once the bracket itself wears at the roller stem the cable angle changes and fraying accelerates, as it did on this Forrestfield door.
