Tighten garage door chain.

Tightening your garage door chain is a simple matter of turning the right nut. Using your wrench you can start to loosen up the adjusting nut on the side of your carriage closest to the opener head. Chain adjusts by shortening the chain itself. Twist the outer nut clockwise with the wrench to move the trolley and tighten the chain.

Turn it counterclockwise holding the other nut in your hand to prevent it from turning. Both adjustment types should be done with the door closed and disconnected from the opener using the emergency release. Slowly turn the outer nut as you watch the slack on the chain above your chalk mark. The trolley is responsible for pushing or pulling the opener arm along the chain so as to open and close the garage door.

Then use the wrench to tighten this second nut clockwise until the chain is tighter but not so taut that it is completely inflexible. The one you re looking for is attached to a bolt found at the spot where the trolley or carriage connects to the rail. There are only a few ways that the chain can be tightened.
