Two Cables Hold Up the Whole Door
Every sectional door hangs from two steel cables, one per side, each running from a low bracket to a cable drum fixed on the spring bar. They are the link between spring power and door movement, which makes a worn strand more serious than it looks.
Should the door in your new garage lean to one side or a cable appear furry, leave the opener off. Our replacement uses cables cut to suit your door's height and load, and we examine the drums, pulleys and brackets that age beside them. Otherwise a mismatched part lets the door tilt again.
What Worn Cables Look Like
Strands splaying outward
Check the stretch near the bottom bracket and the spot where cable meets drum. Wires that poke out, or a cable that has opened like a frayed rope, are nearing the end.
A corner sitting low
If one side rides lower than the other, a cable may have slipped or parted. The door then twists as it moves, and continued use can bend its sections.
Slack cable on the shaft
A loose, looping cable around the drum shows the door has been rising unevenly for a while. The drum grooves can be scarred, which would shorten any new cable's life.
How Replacement Goes
- 1
Lock the door down
The door is held in place and spring tension is dealt with first. A cable that comes loose under load can release a surprising amount of force.
- 2
Match the new cables
Replacement cables are cut for the door's height, and worn drums, pulleys or brackets are renewed alongside, so the new cable winds in cleanly.
- 3
Level both sides
Tension is evened out left to right. We raise the door by hand, watch it climb square and then run several full cycles with the opener.
Cable Questions From New Owners
- If one cable breaks, do I need two new ones?
- Usually it makes sense. The two share the weight and wear at the same pace, so the survivor is often tired too. Replacing both also lets us set equal tension, which keeps the door from twisting as it rises.
- What makes a cable slip off its drum?
- A loss of spring tension, a bent track or a bump from a car can all let a cable jump its groove. Once it has kinked, a new cable is the safer route, because rewinding the damaged one risks another slip.
- Can I reattach a cable myself?
- We would steer you away from that. Cable and spring tension are tied together, and a door that shifts without warning can crush fingers or fall hard. Keep the opener unplugged, stay out from under the door and give us a ring.
Is One Side of the Door Lower?
Hold off on using it and unplug the opener. Tell us the door's height and describe the cable, then expect a clear explanation of the repair.
