Light Rail 3 Extender Rail
LightRail 3.0, 3.5 and 4.0 one meter (39″) Extender Rail. (LR3 RX) Extender Rails have a variety of uses. When added to the standard 2 meter rail, they can be used with the Auxiliary Trolley, to aid in festooning vent tubing, or with the Add-a-Lamp parts to run 2 lamps in a 9 foot configuration (3m), instead of a 12 feet configuration (4m). Another use might be to run high intensity lights over 9 feet during periods of less light needed.
