TL;DR
Horizontal track is the pair of overhead rails that carry a sectional garage door's rollers once the door rises past the curved transition, suspended from the ceiling by angle-iron hangers and pitched slightly upward toward the rear. Its radius, 12 or 15 inches typically, must match the vertical track and drum set, and bent or out-of-level rails make doors jump, bind, or fall off the rollers.
What it means
Horizontal track is the pair of overhead rails that carry a sectional garage door's rollers once the door rises past the curved transition, suspended from the ceiling by angle-iron hangers and pitched slightly upward toward the rear. Its radius, 12 or 15 inches typically, must match the vertical track and drum set, and bent or out-of-level rails make doors jump, bind, or fall off the rollers. Door techs check hanger bolts and back-hang bracing during tune-ups because loose track is both a noise source and a safety issue.
