QUICK ANSWER
Door jerky or leaning on an extension-spring setup? A worn pulley may be the cause. Keep clear and call us, since a failing pulley can drop the door.
Pulleys guide the cable on extension-spring doors. A worn pulley chews through the cable and can make the door lurch.
Why pulleys fail
Wear and age
Plastic and steel wheels crack with use.
Rust
Damp garages seize the bearing.
A frayed cable
A rough cable chews the groove.

Get today’s pricePulleys and the safety cable
Doors with extension springs use pulleys at the spring ends, and a safety cable runs through the spring. A broken pulley can drop the door suddenly. We replace worn or cracked pulleys, check the cables, and confirm the safety cable is in place, since a loose extension spring can whip when it breaks.

Questions about pulley replacement
What do pulleys do?
On doors with extension springs, pulleys guide the cable. A worn pulley can fray the cable or let the door drop.
Is a safety cable necessary?
Yes. A safety cable runs through an extension spring so it doesn’t whip if it breaks. We check it during a pulley replacement.
