The garage door is most often the sturdiest and the heaviest part of your home. It is usually made from a durable material, either from hardwood or from metal. Through the years of use, the garage door will experience wear and tear. This includes certain parts getting rusty and loosening up.
If your garage door doesn’t fully open up, feels heavy when being pulled up, or bangs hard when it does, the tension needs to be reset. This is where you need to adjust your garage door. However, this can be a difficult task for first-timers.
Here are the steps to take in order to adjust it easily like a boss:
Get the right tools. Scour through your tool box for the tools that you will need in finishing this task. You will need two combination wrenches, a four-inch nail or pin, Allen keys, and a self-grip wrench or C-clamp. All these will help you in adjusting the tension spring of your garage door. You might want to get a ladder, in case you need to climb up to reach the springs. Use safety goggles for eye protection, as well.
Prep your garage door. If you have a garage door opener, it might be best to unplug it before you start working on the tension of your garage door. In addition to that, you need to check where the torsion springs are located. Smaller garage doors usually have this on top while larger ones are located at either side. This is where you’ll do the adjusting of the tension knots.
Lock the end of the steel rod with a clamp. Clamp the end of the rod and put a nail or pin in the spring anchor. Make adjustments with your clamp by turning it to ensure that the nail comes out on the other side. This secures one side of your tension spring while you work on the other more important side. For those with larger doors, you need to use two C-clamps to keep the door open while you’re working on the tension knots.
Adjust the tension. Use two wrenches to hold the spring tension knot while you use a 4mm Allen screws to loosen the two grub screws found on the knot’s body. There might be instances when you need to adjust both screws and times when you just need to adjust one. When adjusting the grub screws, always control the tension with the wrenches. Never remove them as this will remove all the tension on the spring and make the garage door useless. You might need to turn the knot upwards with another wrench to reach the other grub screw and adjust the tension. Remember, you turn up the knot to tighten and downwards to loosen. The number of turns that you have to do depends on your garage door opener. While you’re turning the knot, make sure that you feel the tension and not let it go. If you feel a good strong tension, lock off the grub screw. Allow it to turn a little and lock the second grub screw. Once you’ve got it the way you want it, lock up the grub screw. You have to tighten both grub screws after.
Remove the clamp and test it. After adjusting the tension knot, you can now remove the pin and the clamp. This already allows you to use your garage door normally. Once the clamps are removed, it is time to test it out. Open your garage door manually and pull it up. If it fully opens, then you have adjusted it properly. If it still does not open quite right, then you might need to adjust the tension knot again.
