The Avenger E390 TVMP ADAPTER (YOKE to STAND) is ideal for most TV lighting, LED lights or any lights that have a hole in the yoke for the mounting of a C-Clamp or similar. If these lights need to be mounted on to a baby stand or junior stand, this adapter can do both. The adapter has a 5/8 in female receiver while the outside diameter of the adapter is 28mm/ 1 1/8 in. The TVMP adapter is equipped with a threaded bolt on top that allows for quick attaching to a yoke. A set screw is located below the T-knob and can be used for increased securing and safety. USE with lights with YOKE Mounts: Gemini\'s, Panel Lights, Astras, LED\'s, Fresnel lights and Fluorescent Lights.
