About this product

The Kupo 6" Extension Arm with Universal Adapter Spigot is a professional-grade accessory designed for use with Super Convi or Viser clamps in photography and videography setups. Made from solid aluminum die-casting with a black powder coating, it provides durable support and stability. The arm extends 6 inches and features a 5/8" (16mm) baby receiver to attach lights, cameras, or other equipment. Its removable universal adapter spigot includes both 1/4"-20 and 3/8"-16 male threads for compatibility with multiple clamp systems. A hex-shaped stud at the end securely snaps into the clamp to prevent rotation. This tool enables quick, stable mounting and is easy to clean with a damp cloth.
