Definition
The long track that runs from the opener motor head to the wall above the door, guiding the trolley as it pulls the door open and closed. The rail has to match your door height — a standard rail handles a 7-foot door, and taller doors need an extension kit. A sagging, bent, or poorly braced rail makes the whole system shudder and wears the drive prematurely. Rail alignment is one of the quiet details that separates a tidy professional installation from a Saturday-afternoon one.
