A man door is a standard swing-style door that is built into a garage door. It may also be referred to as a pedestrian door, a pass door or an access door.
A man door is a convenient way to enter a garage without having to raise or lower the entire garage door, thus preserving privacy and conserving energy. In addition to protecting the contents of the garage from view, using a man door minimizes the air exchange from inside to outside. Using a man door also reduces wear and tear on both automatic garage doors and the remote-control devices used to operate them.
