The QR modules allow you to attach the module to your accessory or camera/cage/support, and then mount the arm on the module and secure it with the dual locking system. This makes it easier to attach the arm to your camera or accessory, as you don't have to contend with the length of the arm or that it is already attached to the camera or accessory. It also enables you to leave just the QR attached to the module when packing your gear away, and you can source additional modules and pre-attach them to your accessory for an even faster workflow.

This module features a flip-up twist tab that lets you engage either the 1/4"-20 thread or raise a 3/8"-16 sleeve around the 1/4"-20 screw. Continuing to twist the tab engages the ARRI-compatible anti-twist pins. Reversing the direction of the twist disengages the pins, and then the sleeve.
