Overview

The Kupo KG008512 Long Double Baby Stud is a grip rigging connector designed for photographers and videographers who need a reliable way to join clamps, grip heads, and lighting accessories. At 4.9 inches in length, it is longer than a standard double stud, providing additional spacing between connected components. This extra reach is valuable when rigging in confined spaces or when you need clearance between a clamp and the fixture it supports — for example, when a Convi Clamp grips a pipe or truss and needs to offset a grip head to avoid physical interference.

Built from chrome-plated steel, the stud is engineered to handle the loads and stresses of professional lighting setups without bending or slipping. Both ends feature the industry-standard 5/8-inch baby pin, ensuring compatibility with virtually any grip head, clamp, or receiver on the market. It is a small, inexpensive piece of hardware, but one that solves a specific and common rigging problem — and having several in your grip bag means you are always prepared for creative mounting solutions on set.
