Overview

The Kupo KG019312 is a 12-inch baby stand extension built from chrome-plated steel for professional lighting and grip applications. It serves a simple but essential purpose: adding height to baby pins, light stands, baby plates, and grip arms so you can position fixtures, modifiers, and accessories precisely where they need to be. The extension features a standard baby 5/8" pin with a knurled neck — the textured surface ensures that when a set screw tightens against it, the connection holds firm without rotation or slippage, even when supporting heavier fixtures or during frequent repositioning on set.

Versatility is built into the design through multiple mounting interfaces. The top of the extension includes an integrated 1/4"-20 female thread, providing a direct attachment point for accessories that use the standard photographic thread size. At the base, removing the locking knob converts the receiver from baby to junior compatibility, expanding the range of stands and sockets the extension can work with. The chrome-plated steel construction is built to endure the realities of professional production — repeated rigging adjustments, transport between locations, and long-term studio use. Whether you need extra reach for an overhead light, elevated positioning for a flag, or simply a reliable adapter between grip system components, the KG019312 is a dependable addition to any grip kit.
