Overview
The Kupo KS-034 28 mm Stud with M10 Bolt is a heavy-duty professional lighting spigot designed for secure mounting of lighting fixtures onto standard 28 mm (1-1/8") junior receivers used in film production, television, theatre, photography, and broadcast environments.
Built from solid chrome-plated steel, the KS-034 is engineered for strength, durability, and long-term reliability in demanding on-set conditions. It features a 28 mm TV spigot on one end, designed to fit standard junior receivers, and an integrated M10 threaded bolt system with washer on the other end for securely attaching lighting fixtures to yokes or compatible mounting points.
A key design feature is the additional safety pin hole, which allows the user to insert a secondary locking pin for added security during overhead or load-bearing applications. This makes it particularly suitable for professional lighting setups where safety compliance and fixture stability are critical.
The direct bolt-through design ensures a firm connection between fixture and stand interface, reducing play and improving alignment consistency across repeated setups.
