It includes a LightRail 5.0 Auxiliary Trolley, a crossbar, a push/pull rod, mounting hardware and instructions. And, the Add-A-Bar adjustable width settings are 81”, 87” or 93”. Also, if a third crossbar is needed, you will also need to purchase a 4 foot LightRail 5.0 Auxiliary Rail. Hint: Most people have each crossbar travel in its own 4 foot Rail half section. And, that’s with about a 2’ gap between those 4 foot Rail sections. Indoor plant light will fill in the gap area from both sides.
