Overview

The Kupo KG091112 Stand Stud is a straightforward adapter that solves a common problem in studio and location setups: mounting accessories with 3/8" holes onto light stands that have 1/4"-20 male tops. Background crossbars, certain clamps, and other mounting hardware frequently use the 3/8" standard, and this small adapter bridges that gap without requiring a different stand or a bulky workaround. The knurled pin design ensures you can tighten it securely by hand, maintaining a firm hold even when adjusting positions during a shoot.

Built with a silver-plated finish, the KG091112 offers better resistance to wear and corrosion than bare metal alternatives, a meaningful advantage for adapters that see constant threading and unthreading. Its compact size makes it easy to toss in a pouch or tape to a stand leg so it is always within reach. For photographers and grip technicians who work across different equipment brands and mounting standards, this adapter is the kind of small, reliable piece that keeps setups running smoothly without delays.
