Garage Door Safety Cables Intro
Garare door safety cables are put into place in order to protect against dangerous spring recoils. Garage door springs are under extreme pressure. At the very least a spring mishap can cause both extensive and expensive damage to property. It can also result in serious mortal bodily injury. It is better to call a garage door professional to handle this type of repair, if owners are inexperienced. It may cost slightly more to hire someone; however, it can save pain, suffering, and money in the long run.
Release the Pressure
Warning: It is vitally important to release the tension of garage door springs prior to attempting to perform any type of repairs to them or, in many cases, any mechanisms in conjunction with them.
* Raise the garage door completely to the open position.
* It may be necessary to clip the cable in the track in the event that the door will not move. Use c-clamps to prevent the garage door from closing or abruptly dropping during the replacement process. Place the c-clamps on the track on the bottom of the door right below its lowest wheel.

* Once the door is secure and locked open, it should be simple to disconnect the springs, replace the cables, and reconnect the springs. Remember do not, under any circumstances, disconnect the springs prior to releasing the tension.
* Secure a pair of vise grips right below the outer edge of the cable shaft. Move the vise grips counterclockwise in order to release the pressure on the shaft. Rotate only enough to loosen the cable. If the cable is loosened too much, the slack will cause to become entangled.
* Use a flat screwdriver to remove the cable loop from the garage door. It will probably be necessary to slip the screwdriver behind the cable loop to do so.

* Coil the cable around the pulley gear until there are only about 12 inches remaining.
* Locate the connector on the garage door and slip the loop end over this.
* Turn the shaft and tighten it. During this process ensure that the garage door cable remains inside the two edges of the pulley gear. Continue tightening it until all of the slack is removed from the cable.
* Remove the c-clamps from the track.
