When there are no easily accessible structures near the track a threaded rod assembly can be secured to these supports. The threaded rod can be secured to a structure near the ceiling of the building and significantly above the track system. The A3242-1 coupling nut is used to secure two adjacent lengths of threaded rod. The 16TBTR Track Bracket Threaded Rod can be secured to a 16CT Curved Track when curved systems are used. The A3120-2 Edge Clamp is used to secure threaded rod to the edge of a roof truss section, beam or channel.
