Two factors determine the type of cables suitable for a particular garage door - the door's weight and length of cable. Length of the cable is not gauged simply by the length of the garage door, as the technicians need to factor in the mechanism of garage door operation, the type of spring system, thickness and weight of the garage door. The two primary spring systems, torsion and extension, determine the type of cable ideal for your garage door.
The torsion springs need a relatively shorter height of garage door cable - just a foot more than the height of the garage door. In an extension spring system, the cables are four times the length of those used in a torsion system. The simple reason for this is an extension spring system uses a pulley system for operating the garage door. In a pulley system, the cable needs to run from the back of the door and then the same length at the front of the door where it is attached. Moreover, there is also a safety cable that runs through the garage door spring's centre. This prevents the cable from causing any injury. That's why you need a 30 feet cable from both sides equalling 60 feet in total in an extension spring system.
Both raw and assembled cables are available for standard as well as custom lengths of garage doors. Some common custom length garage door cables include a 1/8
