There are four types of garage door openers we can choose from, but all of them come with a motor that can move a trolley. Here are the types of garage door openers we can find.

  • Chain Drive: The chain drivers are best used for our garage doors detached from our homes. But if our garage is just under our bedroom or living room, we might want to choose another type of garage door opener.
  • Belt Drive: If our garage area is located near our bedroom or living area, this drive is the most recommended garage door opener for us.
