The Handle Extensions follow the design of the Camera Center Handle CCH-4. The number of each HEX refers to the number of 3/8-16 interfaces on the top (HEX-1 has one and HEX-5 five of them). They can be connected in multiple ways in order to extend a top handle but also to build your own handle design. Every HEX offers a 3/8-16 screw at the front (ARRI Multi-HEX screw with 4 different tool options) with two anti-twist locating pins and the corresponding thread interface at the back. Multiple RMB-3, as well as 1/4-20 interfaces, are included as well. The system can also be used to build a so-called "Hollywood Handle". This allows to operate the camera from the back without touching the on-board battery. The Handle Extension Set comes in a foam inlay that fits in a Pelican 1170 case (Pelicase not included).
