Turn it counterclockwise holding the other nut in your hand to prevent it from turning.
Tighten the chain using the tension nuts after verifying the chain needs tightening begin by turning the inside nut which is the one closest to the opener several turns in a counterclockwise direction when facing the door.
This will cause the nut to back away from the door and toward the opener.
Tightening your garage door chain is a simple matter of turning the right nut.
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 s usually a piece of rope hanging from it which is used to disengage and re engage the opener.
