Your garage door chain drives your door, so it’s a vital part of any garage door opener system.

In this short video clip, Jacob Swenson of Specialized Garage Doors in Salt Lake City, Utah, walks us through the process of adjusting your door chain.

Safety Points

  • Although the video doesn’t mention it, unplug the unit before adjusting your garage door chain. If you do not, you’ll run the risk of the opener engaging and hurting someone.
  • The trolley needs to be disengaged while adjusting tension.
  • Slack b/w the chain and rail should be 0.5 inches at midpoint, when open.
