The heavy-duty Light Rail 5 is an adjustable, self-propelled light mover that transports a light system along a 6' aluminum rail. Simple, lightweight and easy to install, it features a 4 RPM instrument-grade Intelli Drive Motor with steel-on-steel bearings and sure-grip dual drive design. These motors pause at each rail end for a customized time period from 0-60 seconds. The triple-duty aluminum track coupled with the wide and stable carriage on the Light Rail 5 can even support two or three reflectors simultaneously. 90+ lb. capacity if properly balanced. From the all new "triple duty" extruded aluminum track, super "wide-n-stable" carriage with steel on steel carrier bearings, to the high torque instrument grade drive motor with ball bearing output shaft and "sure grip" dual drive design. The new Light Rail 5 is more than capable of moving 2 or 3 lamps, side by side or fore and aft. The Light Rail 5 is backed by a limited lifetime warranty.
