Overview

The Kupo KG006812 Double Sided Hex Joining Stud is a purpose-built steel adapter that bridges two Convi Clamps or Super Clamps, creating a back-to-back connection with full 360-degree rotational freedom. This makes it an indispensable component for photographers and videographers who rely on modular clamp-based rigging systems to mount lights, flags, reflectors, and other gear in the studio or on location. The dual hex ends accept a wrench for secure tightening, which helps prevent unwanted loosening during use — a critical feature when supporting heavy or awkwardly positioned equipment.

Built from solid steel, the KG006812 is designed to handle the demands of repeated professional use. Its straightforward form factor keeps setups compact while providing the structural integrity needed for reliable overhead or angled rigging. Whether you are assembling a complex multi-clamp frame or simply need to join two clamps for a quick on-set solution, this joining stud delivers dependable performance without unnecessary complexity.
