The RAAD2 adapter is an adjustable clamp designed for the 3XD gimbal. The body of the adaptor is round and sits around the upper handle of the 3XD. The inside of the frame is designed with foam to protect your handle from getting scratched. The lock knob can be adjusted to fit around different areas of the handle if necessary. One ¼” thread hole and one 3/8-16 thread hole are designed to attach other gear such as an adjustable arm, a microphone, or monitor. RAAD2 is compatible with 3XD gimbals.
