Featuring dual mounting surfaces on both sides of the clamp. The Dual Clamp allows two Arca Swiss compatible plates or rails to be mounted in a parallel orientation side by side or with one atop of the other. Together with the Upright Foot and lens rings, it forms a compact and light weight rig for capturing 3D stereoscopic panoramas. This dual clamp can also be mounted to the upper rails of NN3 MK3, and NN6 series heads which would allow for acra swiis style mounting of camera.
Small screws at the edge allow a plate or rail to be fixed to the Dual Clamp, independent of the main locking knob of the clamp. This allows lens rings to be mounted one by one safely and allow the Dual Clamp be fixed to one rail while moving or adjusting the second rail. This feature is ideal when mounting a lens ring or telephoto lens plate atop of another rail.
Because both clamping jaws are simultaneously closed by the main locking knob, all plates or rails used with the Dual Clamp need to have exactly the same dovetail.
