Kupo KG500511 Large Gaffer Grip Clamp

The Kupo KG500511 Large Gaffer Grip Clamp is built for the practical reality of production rigging — securing lights, flags, nets, and grip accessories to whatever structure a stage or location provides. Its 1/4" to 3-1/8" adjustable jaw range covers the majority of surfaces a gaffer encounters: speed rail, C-stand extension arms, door frames, pipe grids, and set dressing with mixed round and flat cross-sections. The removable 5/8" baby pin, mounted in a female receiver, collapses two rigging steps into one — the clamp attaches to structure and simultaneously provides a direct mount point for any baby-pin–compatible accessory, from a small LED fixture to a flag arm.

Construction follows Kupo's production-grade standard: finished in non-reflective black and built to withstand the mechanical stress of repeated setup and breakdown without loosening or losing clamping consistency over time. The variable tension control knob is a functional differentiator from simpler spring-loaded designs, giving the operator direct control over jaw pressure when mounting to surfaces — painted flats, furniture, or finished architectural elements — that can be marred by over-tightening. For studio and location crews looking to reduce the number of specialty rigging pieces in the grip package without sacrificing holding reliability, the KG500511 is a practical first choice.
