Get Help With Torsion Systems
If your garage door cables need replacement and you have a torsion system, it is best to have a professional perform this task. Torsion springs store a lot of potential energy - after all, they do the majority of the work in lifting the door and must be "unloaded" to allow the cable to be replaced. This is a task that can be very dangerous if not done properly. Some caution here and professional help will ensure that no one gets hurt.
