MovoCAB1000 15mm Modular Rod Clamp Adapter - Mounts Cameras, Monitors, Recorders to Rigs with Multiple 1/4" and 3/8" Male/Female Mounting Threads

Dont buy it unless you really need it. Buy smallrig gear that costs the same and performs properly. This clicks and clacks and can be moved even when tightened beyond maximum. Yikes.

Used this to mount quick release plate and remote for camcorder rig. Looks and works great.

Exactly what I needed built well also
