Overview

The Kupo KG601812 Pivoting Boom Arm Clamp is a specialized grip accessory designed to extend the functionality of your existing C-Stand equipment. Rather than purchasing a separate boom arm assembly, this clamp allows you to repurpose a C-Stand riser section as a boom, giving you overhead and offset positioning capability for lights, flags, scrims, or other accessories. The body is constructed entirely from aluminum die-casting, ensuring it can bear the mechanical stress of boom-mounted loads without flexing or slipping.

The clamp features two standard professional mounting interfaces: a 1-1/8" (28mm) junior male pin and a 5/8" (16mm) baby female receiver. These fittings are widely used across professional grip and lighting hardware, making the clamp compatible with a broad range of stands and accessories. An internal insert secures boom tubes in the 1.2" to 1.4" (30–35mm) diameter range, and the pivoting mechanism lets you dial in the precise boom angle before locking it down. For studio crews and on-location professionals looking to maximize the versatility of their C-Stand inventory, this clamp is a practical and space-efficient addition to the grip bag.
