How To Tighten Garage Door Chain

A loose chain on your garage door can cause a number of problems, including:

The door may not open or close properly.
The door may make noise when it opens or closes.
The chain may break, which could cause the door to fall.

If you notice that the chain on your garage door is loose, it is important to tighten it as soon as possible. Here are the steps on how to tighten garage door chain:

Disconnect the garage door from the opener. To do this, pull the emergency release cord, which is usually located near the motor unit. This will disengage the door from the opener and allow you to move it manually.
Raise the garage door to the open position. To do this, lift the door by hand until it is fully open.
Locate the chain adjustment bolts. These bolts are located on either side of the door, near the top of the tracks. There will be two bolts on each side.
Tighten the chain adjustment bolts. Using a socket wrench, tighten the bolts until the chain is snug. Do not overtighten the bolts, as this could damage the chain.
Reconnect the garage door to the opener. To do this, simply pull the emergency release cord again. This will re-engage the door with the opener.
Test the garage door. Open and close the door several times to make sure that it is working properly.

Here are some additional tips for tightening garage door chain:

If the chain is very loose, you may need to remove a link or two.
If the chain is frayed or damaged, it will need to be replaced.
It is a good idea to inspect the chain on your garage door every few months and tighten it as needed.
