A handy & compact accessory, the StandCuff 1-V from Fotodiox secures to light stands, c-stands, tripod legs, overhead rigs, etc and allows you to attach a V-mount battery so you can power a nearby light, monitor, or other accessory. Clamping the battery to a tripod leg or light stand and powering your camera or light by a power cable minimizes the weight supported by the tripod head and simplifies balancing your rig. The clamp will attach to any pipe from 25mm (0.98 ) to 35mm (1.38 ) and is made of hardened anodized industrial aluminum alloy. The jaws of the clamp completely encompass the pipe and lock securely in place for safe and secure attachment of up to 110lbs (50kg).
