Kupo Round Stud with 3/8"-16 & 1/4"-20 Thread (KS-014R)

Overview

The Kupo KS-014R Round Stud is a compact, professional-grade rigging adapter designed to provide a versatile threading solution for lighting, camera, and grip equipment in film production, television, theatre, and photography environments. It is commonly used within the Kupo Convi Clamp system ecosystem to enable fast and reliable connections between accessories with different thread standards.

Manufactured from solid brass, the KS-014R offers excellent durability and corrosion resistance while maintaining a lightweight, compact form factor ideal for daily use on set. The stud features dual male threads—3/8"-16 on one side and 1/4"-20 on the other—allowing seamless compatibility with a wide range of industry-standard camera and lighting accessories.

Unlike hex-style variants, the round body design provides a smooth, simplified profile, making it suitable for applications where clearance or rotation is less restricted. It is frequently used as a replacement or universal adapter in grip kits, umbrella adapters, swivel mounts, and small rigging assemblies.
