From its “triple duty” extruded aluminum track, “wide and stable” carriage with “steel-on-steel” carrier bearings to the high torque 4 RPM instrument grade drive motor with ball bearing output shaft and “sure grip” dual drive design, it is more than capable of moving 2 or 3 lights side by side or fore and aft per cross bar and as many as 9 lights (or six lights to accommodate larger hoods) with the available add on products. It comes with LR5 Drive Motor, crossbar, instructions, mounting hardware and a 2 section 8 foot rail so it’s long enough and ready for an extra Add-a-Bar Kit.
