How to Adjust Garage Door Cables

What You'll Need
A G clamp for holding the cable spring in place
A metal bar to slide through the hole on the edge of the collar
Safety goggles
Safety gloves

Garage door cables can be adjusted by the home handyman with patience and a few tools. It’s a typical do-it-yourself kind of job. As the springs can be fiddly things to adjust, you might need to ask a friend to help you.

Step 1 - Start The Task

If you are starting the task of adjusting the springs to make them tighter and to make the garage door rise in the same way it did when installed, it’s a good idea to have a friend help you. Your first task is to release the springs by using the clamp to the door roller. Do this at the lowest point.

Step 2 - Check the Pulleys

Once this is accomplished you need to make sure the pulleys don’t need replacing.

Step 3 - Adjust the Springs

You can now adjust the springs to a tighter setting by moving the S hook higher. Make sure you adjust it by placing it into the hole higher on the track.
