The HEX-90 is part of ARRI's handle extension family. It can be used to extend the handle system behind the camera or battery downwards to build a so-called "Hollywood Handle". This enables operating the camera from the back without touching the onboard battery. In combination with the CCH-2 (K2.73002.0), the CCH-2 Support (K2.0038176) is recommended for increasing the load limit and sturdiness of the CCH-2
