The DJI Ronin Twist Grip Dual Handle allows you to use your DJI RS 2/DJI RSC 2 in various configurations, such as with both hands or briefcase mode, which is thanks to the NATO ports that are built-in to the unit.
In addition, the handle has a quick-release design & mechanical handles on either side which can be replaced by DJI's Ronin Tethered Control Handle.
Both horizontal arms include 3/8''-16 and 1/4''-20 tapped holes as well as cold shoe ports for different accessories.
