The Kupo KS-344 is an accessory for the Kupo KCP-110 Rock's arm. Adding the KS-344 to a Rocks Arm adds the Arri style anti-rotation connector, a widely used connection in the video and cinema industries regularly found on camera cages. Integrating a knurled tightening knob makes it easy to lock the Rocks Arm onto your equipment by hand via the thumbscrew.

The KS-344 includes a #3 Allen Key hole to allow you to securely lock it in place.
