Kupo Super Knuckle Claw studio clamp

The Kupo Super Knuckle Claw is a modular mounting tool built for photographers and videographers who need secure attachment points on set. It combines a mini claw clamp with a ball joint, allowing gear to be fixed to surfaces ranging from 3/16" to 3/4" thick. The system uses a central knob to lock both joints at once for faster rigging. Condition is new.

Replaces separate clamps and arms

This unit replaces the need to carry a standalone mini clamp plus a separate articulating arm or ball head. The jump is worth it when you regularly mount lights, monitors or accessories to pipes, rails or boards and want a single piece that clamps and positions in one step. It suits crews who value speed over building a custom rig from loose parts each time.

Fits into grip kits and rigging workflows

The claw end grabs onto light stands, C-stand arms, pipe grids or set walls while the ball joint accepts any accessory with a matching socket or stud. The central locking knob frees up time by securing both axes together, reducing the number of knobs to adjust during a shoot. It integrates with the wider Kupo Super Knuckle modular system for expanded configurations.
