The Manfrotto FF3230 is a single 4 wheel sliding carriage with a 0.625 inch/16mm spigot that fits SkyTrack Systems ceiling grid. It is rated for normal weight loads up to 132 pounds/60kg. It's compatible with all types of lights, whether photographic, video or film.
Ideal for all photo and video studios where the floor needs to be kept totally clear of power cables and lighting stands, the Sky Track System permits rapid maneuver and setting of suspended large lights or lights with awkwardly sized accessories like soft boxes. All items sold separately.
