The guiding mechanism includes a guard bracket extending along the doorway and having a mounting segment and a guard segment, and a track extending along the doorway and including a guideway for receiving a roller of the extension member and for guiding the roller as the door moves between blocking and unblocking positions. The track is affixedly mounted to the mounting segment such that the guard segment protects the track from an obstacle during a track impact condition.
