Overview
The Kupo KS-015R Round Stud is a compact professional Convi Clamp adapter designed to provide flexible mounting options for lighting, camera, and grip equipment in film production, television, theatre, photography studios, and live event environments.
Manufactured from solid brass, the KS-015R offers durability and corrosion resistance while remaining lightweight and easy to integrate into any grip kit. Its round body design allows it to sit neatly within compatible 16 mm (5/8") receiver systems, providing a clean and simple interface for mounting accessories without adding unnecessary bulk.
This version features dual female threads (3/8"-16 and 1/4"-20), making it highly versatile for connecting a wide range of industry-standard male-threaded equipment such as cameras, ball heads, lighting adapters, and rigging accessories. It is commonly used as a replacement stud or universal connector within the Kupo Convi Clamp ecosystem, particularly in applications requiring fast thread adaptation on set.
