A wheeled top guide for rolling movement of a door along an inverted U-shaped track includes a housing for mounting on the door with an upwardly-extending axle and a roller thereon for rolling engagement with one side wall of the track. A vertically- oriented torsion member is seated in the housing and has a vertically- extending elongated torsion rod having its lower end fixed on the housing, a horizontally- extending arm having one end secured to the upper end of the torsion rod and extending away from the first axle, and an upwardly-extending axle adjacent the other end of the arm. A second roller on this axle is in rolling engagement with the other side wall of the track and is spaced from the first roller. The second roller and arm are resiliently displaceable about the longitudinal axis of the torsion rod towards the housing for insertion of the rollers into the track, and the resulting torque in the torsion rod produces a force biasing the arm and thereby the second roller to maintain the rollers in firm rolling contact with the side walls of the track.
