The iDC Photo Video SYSTEM ONE 16" UniRail lets you accurately position and balance the camera and Gearless Follow Focus assembly.
Featuring a double-dovetail design, this UniRail can be directly mounted onto many fluid heads and monopods with no adapters or quick-release plates required thanks to the industry-standard 3/8"-16 and 1/4"-20 threaded bosses. You can also use the Manfrotto 577 Rapid Connect Adapter to adapt your fluid head to have direct compatibility with the UniRail.
The top surface of the SYSTEM ONE UniRail is machined to be Arca-Swiss friendly and acts as the foundation for the iDC Gearless Follow Focus. The sliding clamp design when coupled with the Gearless Follow Focus, allows you to use a wide variety of lenses without the need for separate ring gears for each and every lens in your kit. The UniRail is bi-directional and features two 1/4"-20 through holes for additional accessory mounting options at both ends.
