What Do Garage Door Cables Do?

Step 1: Safety measures

Safety is the most important consideration in any home improvement project. This is especially true for garage doors.

It is always a good idea to have assistance on hand when you are dealing with something as heavy as garage doors. This type of project requires safety precautions such as gloves and eye protection.

Step 2: Remove the cables

Next, you will need to open the door as far and as wide as it will allow. Then, place a step ladder underneath the door. Two pairs of locking pliers, or C-clamps, should be taken and locked onto the track under the last roller. This will prevent the door from opening unintentionally.

Find the side with the broken cable, and work your way up. A winding drum will be found on each side of the door at the upper corners. You will likely find any remaining cable here. Locate the end of the cable in the drum at the drum’s outer edge.

Take care to unwind the cable. The cable’s other end will be looped around the pin on the bottom, just below the outer edge. Take the cable off the pin.

Step 3: Install new cables

Now it is time to install your new cable. The cable you receive should exactly match the original. If the new cable looks different, it’s likely you are using an incorrect cable. Do not proceed if you have the wrong cable.

If the cable looks good, find the end without the loop. Then place it in the drum’s notch. Use the grooves in your drum to guide the cable during garage door repair. Continue winding the cable until you have enough material to reattach the pin on the bottom of the door.

Slide the looped cable end onto the pin. Now you can remove the ladder and clamps to test the operation. You won’t have to worry if there are small gaps between the cable winds and the drum. After a few cycles, the cable will align into the drum grooves.
