Definition
The steel channels that guide the door's rollers: vertical track runs up each side of the opening, horizontal track runs back along the ceiling, and the curved radius section connects the two. Track must be plumb, parallel, and solidly anchored — a track bent by a car bumper or loosened by years of vibration is the usual reason a door jumps its rollers and goes off-track. Track problems rarely fix themselves; small misalignments grind rollers and hinges until something fails.
