The Sunwayfoto DLC-60 Duo-Lever Clamp is an Arca-style clamp that features a knob on one side and a lever on the other. The screw knob allows adjustments to the width of the clamp, and the lever locks and unlocks it. With its adjustable width, the clamp enables fast, lever-driven release & securing of most Arca-style dovetail camera plates (from Arca-Swiss, Really Right Stuff, Kirk, Markins, etc.).
The DLC-60 fits onto any 3/8"-16 threaded screw and includes an M6 Allen screw for attachment to many heads. An integrated bubble level allows you to ensure that your camera's position hews to the horizon.
