Kupo Super Knuckle with Hex Baby Pin

The Kupo Super Knuckle System with Hex Baby Pin is a modular support accessory designed for lighting and camera equipment. It uses a double-ended shell that holds two ball joints, tightened by a single central knob, giving complete freedom to position accessories. A hex baby 5/8in pin on one side attaches to clamps and grip gear, while a locking thumb wheel with a 1/4in-20 male thread on the other mounts cameras or accessories with female 1/4in-20 threads. The system supports up to 17.6 lbs.

Ideal for photographers

This system suits creators who want a single knob to lock both joints simultaneously and the ability to swap accessories on either end. It is not for buyers who need a fixed rigid arm without ball-joint articulation. It is also not for setups that require a load capacity above 17.6 lbs or a different thread size than 1/4in-20 on the camera side.

Check your gear before ordering

Verify that your clamp or grip accessory accepts a 5/8in hex baby pin. Confirm the camera or accessory you intend to mount has a female 1/4in-20 thread. Ensure the combined weight of your mounted equipment stays within the 17.6 lbs limit. No other mounting hardware is included.

Questions about this item

What equipment must I already own to attach the 5/8" hex baby pin to a light stand or clamp?

You need a light stand, C-stand, or grip accessory that accepts a standard 5/8" receiver, such as a convi-clamp or grip head, to mount the hex baby pin securely.

Will the 1/4"-20 male thread on the locking thumb wheel work with my older camera bodies that use the same standard tripod thread?

Yes, the 1/4"-20 male thread is an industry-standard size compatible with virtually all camera bodies and accessories featuring a female 1/4"-20 thread, regardless of age.

How can I verify the Super Knuckle is holding my 17.6 lbs load securely after I position it?

Tighten the central knob until both ball joints lock firmly; the rig should not drift or sag when you release it, confirming the mechanism is engaged.
