Rollers and Tracks
Other essential garage door parts are the rollers and tracks. These pieces guide the entry hatch as it moves up and down. The rollers are the small wheels that run along the side of the panels, and they move on the metal rod tracks that extend from the floor to the ceiling. The tracks control the rollers as they move up, guiding the door into place.
Panels and Hinges
When it comes to garage door parts, panels are often overlooked. That is because most people think of the system as one piece of vinyl or wood. In reality, however, several long panels connected by hinges create each entry hatch. The total number of panels is dependent on the size of the opening; typically, there are around six to eight. These individual panels allow the system to roll up in an arch. The hinges allow the panels to move independently of each other.
