The Kupo KS-200 Junior to Baby Adapter 1-1/8" F to 5/8" M Stud enables you to mount a light fixture or accessory with a baby 5/8" receiver to any stand with a junior 1/8" receiver, such as the Kupo Master C Stand Turtle Base. It's perfect for mounting a light fixture or accessory low to the ground. Solid steel construction gives it superior strength. The bottom of the adapter is drilled with a safety pin hole for use when hanging it from a coupler or clamp with a junior receiver.
