Overview

The Kupo KG005512 is a 5/8-inch baby stud measuring 4.25 inches in length, engineered to serve as a secure mounting interface between lighting fixtures and Kupo's 3-Way and 4-Way clamp systems. Built from solid steel with a chrome-plated finish, this stud is designed to endure the rigors of daily professional use on film sets, photo studios, and live event stages. Its integrated threaded locking collar is a standout feature, allowing users to lock the stud firmly in place and prevent the rotation or gradual loosening that can occur with standard friction-fit pins.

The standard 5/8-inch baby pin interface makes the KG005512 compatible with a wide range of receivers found on light heads, clamps, and grip arms across the industry. A proprietary notch machined into the stud provides additional security when paired with Kupo's own clamp systems, ensuring that heavy or awkwardly positioned fixtures stay exactly where they are placed. For grip technicians and photographers who need a dependable mounting pin they can trust overhead or in hard-to-reach positions, the KG005512 is a straightforward, purpose-built solution.
