SYSTEM ONE 16 Inch UniRail
One of the great features of our UniRail is it's almost infinite adjustability. The position of both the camera and our Gearless Follow Focus assembly can be quickly adjusted and balanced to taste.
iDC SYSTEM ONE is built upon my unique Double-Dovetail UniRail design. The UniRail may be directly mounted onto many popular fluid heads and monopods with no adapters or quick release plates required. Please see the "Specifications" tab for the most up-to-date list of compatible fluid heads. However, if you use another brand of fluid-head or quick-release system, no worries; the UniRail will be quick to adapt via either one of the industry-standard 3/8"-16 or 1/4"-20 threaded bosses provided. You can also use the Manfrotto 577 Rapid Connect Adapter to adapt your fluid head to have direct compatibility (In the "Accessories" tab).
The top surface of the SYSTEM ONE UniRail is machined to be Arca-Swiss friendly and acts as the foundation for our unique Gearless Follow Focus. Our new sliding clamp design is now matched with our unique Follow Focus system and in the iDC tradition, allows the use of a wide variety of lenses without the need for cumbersome and expensive ring gears for each and every lens in your kit. UniRails are bi-directional, and two 1/4-20 through holes for additional accessory mounting options are provided at both ends of the UniRail.
