The F&V Lighting SA1402 Super Clamp is heavy-duty yet light weight and it can be used in a variety of situations. Commonly it is used in a studio setting, allowing you to hang your light on an over head grid. The Super Clamp can also be used to mount your light or accessories on a pole, pipe, or stand. The Super Clamp will work on a tube diameter up to 2 1/4".
The Super Clamp can also be used on flat surfaces, such as shelves, table edges and doors. An additional wedge adapter fills in the gap that allows the Super Clamp to wrap around circular objects. With the wedge filled, the mouth of the Super Clamp is flat.
The Super Clamp has a rubberized mouth to allow for enhanced friction to securely hold your fixture in place. It also comes with a reversible 5/8" stud / spigot. One side of the stud has a 1/4"-20 male thread and the other side has a 5/8"-16 male thread. This can be used to mount additional lights and accessories such as a smaller F&V On-Camera LED Light with an articulating F&V Junior Joint Pro Ball Head.
