Kupo Double Female Thread Camera Stud

The Kupo KS-015 is a compact solid brass adapter with female threads on both ends — 3/8"-16 and 1/4"-20 — weighing just 25g. Designed for use with Convi clamp systems, it lets you join two threaded studs or accessories together, giving a quick way to extend or connect camera and lighting mounts that use either standard thread size.
