The rails & accesories are used to install and extend the track lighting well in the ceiling. They includes rails, different shape connectors, caps, suspension kits with wire, etc. Before you choose these accessories, please make sure you are clear with the difference between 1-circuit/single phase and 3-circuit/3-phase. Each part needs to be matched to its phase type, for example, If you decide to use 3-phase track head, the rails, connectors and others, are needed to use the 3-phase too.
