Overview

The Kupo KG026311 6-inch Extension Arm with Universal Adapter Spigot is designed for production professionals who need a reliable way to extend their mounting reach when rigging lights, cameras, or accessories. Built from solid aluminum die-casting with a durable black powder coating, the arm features a 5/8" baby receiver on one end and a removable universal adapter spigot on the other. The spigot offers both 1/4"-20 and 3/8"-16 male threads, making it compatible with a wide variety of cameras, monitors, and small lighting instruments.

A key design feature is the hex-shaped anti-rotation stud, which locks the arm in place once it is mounted in a compatible Kupo Super Convi Clamp or Super Viser Clamp. This prevents the arm from spinning under the weight of attached equipment, providing stable and predictable positioning. At just 6 inches long, this arm is particularly useful in confined rigging scenarios where a longer extension would create clearance problems or add unnecessary leverage on the clamp.
