Super Knuckle Hex Stud Ball

The Kupo Super Knuckle Hex Stud Ball is a precision-machined accessory that connects lights, monitors and flags to a Convi Clamp. Its 16 mm hex baby stud locks into the clamp without rotation, giving camera crews a stable mounting point for essential gear on set or location.

16 mm hex stud capacity

The CNC aluminium body and stainless-steel hardware support substantial payloads such as LED fixtures and external monitors while resisting slippage. The knurled adjustment knob allows quick repositioning, but the single stud limits the accessory to one mounting axis per unit.

Non-rotating hex connection

The 5/8" (16 mm) hex profile is the decisive specification; it only mates securely with a Super Convi Clamp that accepts a hex baby stud. Builders using standard round baby pins or clamps without a hex socket cannot achieve the locked, anti-twist hold this part provides.

Questions about this item

Will the 16 mm hex stud prevent rotation when I attach this Super Knuckle to my existing Convi Clamp?

Yes, the 16 mm hex baby stud creates a non-rotating connection with the Super Convi Clamp, keeping lights, flags or reflectors locked in position.

How can I verify the knurled knob is clamping securely after I mount a monitor or light?

Tighten the knob until the ball joint holds the accessory firmly without drift; the CNC aluminium and stainless-steel construction maintains that grip under load.

Does the package include the Convi Clamp or only the Super Knuckle Hex Stud Ball?

Only the Super Knuckle Hex Stud Ball is supplied; the Convi Clamp must be purchased separately.
