Known by many other names, this Duck Bill Clamp from Kupo is an industry-standard solution for rigging flat and lightweight light modifiers in professional production environments. The clamp is based around a vice grip platform that is adjustable for accommodating different thicknesses of bead board, foam core, or reflectors. An integrated 5/8" baby pin allows a grip to effortlessly incorporate this clamp into their setups. Once properly set, the clamp's plastic "bill" securely holds the material until the lever is popped open, making this an essential piece of equipment for on-the-fly light modification. It can also be used for holding onto various flat mounting points, like tabletops or wooden doors.
