The RAAD1 adapter is an adjustable clamp designed for the 3XM gimbal. The body of the adaptor is round and sits around the upper handle of the 3XM. 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. Two ¼” thread holes are designed to attach other gear such as an adjustable arm, a microphone, or monitor. RAAD1 is compatible with 3XM (R1) gimbals.
