Kupo 16mm Baby Receiver to 38mm Stud

The Kupo KS-144 16mm Baby Receiver to 3/8" Stud is a black steel adapter weighing 110g that steps a 5/8" (16mm) baby receiver down to a 3/8" diameter stud, letting you mount smaller 3/8" lights and grip gear onto a larger 5/8" light stand. It works in both vertical and horizontal orientations, and a spring-loaded knob with an aluminum casting body provides extra tension for a secure hold.
