Cable Drums – 9 Foot
View part →
Lifting cables in standard 8 and 9 foot lengths and made to measure, plus cable drums and ferrules. The cables carry the door's whole weight between the spring and the bottom bracket, so a frayed one is a genuine safety problem rather than a cosmetic fault.
Cables fray from the inside out, usually where they run over a pulley or wind onto the drum. By the time you can see broken strands on the outside the cable has lost a significant part of its strength. Any visible fraying, kinking or rust means it should be replaced, not adjusted.
The clearest warning sign is a door that sits crooked — one side an inch or two higher than the other when closed — or a door that suddenly drops on one side. That is a cable that has snapped or slipped its drum.
Drums are sized to the door's height. A 9-foot drum has a longer spiral than a standard one so the cable winds on evenly over a taller lift; using the wrong drum makes the cable pile up and jump the groove.
Like springs, cables are replaced in pairs. They wear at the same rate, and one new cable against one worn one puts the door out of level.
Very likely. A door sitting noticeably higher on one side usually means a cable has snapped, slipped off its drum, or stretched. Stop using the door — a partially supported door can drop without warning.
Cable length follows the door height — 8 foot and 9 foot cover most standard Perth doors, and anything unusual is made to measure. If your door is a non-standard height, we can measure and make a set to suit.
No. A cable that has lost strands has lost strength, and there is no safe way to splice one. It gets replaced, in pairs.
