Super Knuckle Ball with 1/4" Screw

The Kupo Super Knuckle Ball is a CNC-machined aluminium clamp designed for photographers and videographers who need a secure mounting point on camera cages or rigs. Its 1/4"-20 thread provides broad compatibility with standard threaded holes found on cages, plates and accessories.

Thumb screw and Allen key hole

A built-in thumb screw allows quick locking without tools during setup, while a dedicated #3 Allen key hole enables easy re-tightening for long-term reliability. These features let users secure the joint firmly and maintain tension over repeated use.

Anti-slip rubber pad and aluminium build

The high-grade aluminium body resists wear in demanding environments, and an anti-slip rubber pad on the base protects mounted equipment from scratches. The clamp integrates with other Super Knuckle components for modular rigging.

Questions about this item

Will the thumb screw or Allen-key hole need periodic re-tightening?

A #3 Allen key fits the dedicated hole for quick re-tightening, and the thumb screw provides tool-free locking whenever you reposition the ball.

What is the maximum load this Super Knuckle Ball can support?

The manufacturer states an optimal load capacity of 20 kg for secure mounting of lights, monitors or other accessories.

Does the aluminum body or rubber pad get hot during extended studio use?

The CNC-machined aluminum and anti-slip rubber pad are passive components with no heat-generating electronics, so they remain at ambient temperature.
