The VCT ARRI M6 Rosette from Zacuto is an ARRI M6 rosette adapter designed specifically for the Zacuto VCT Universal Baseplate (sold separately). It screws into the front of the baseplate on either side and provides support for accessories such as a handgrip. When screwed in, it hangs below the level of the baseplate, so it may interfere when you have the baseplate mounted on a tripod head. For this reason Zacuto recommends incorporating the Zacuto VCT Tripod Plate (also sold separately) underneath the baseplate in tripod applications. The VTC Tripod Plate will allow enough room between the baseplate and tripod head to accommodate the rosette.
