Kupo Baby 5/8in (16mm) Stud 4.25in Long - Compatible with 3 & 4 Way Clamps (KG005512) - Perfect for Stage Lighting, Photography, and Film Equipment Mounting

I bought Kupo’s system for attaching accessories such as arms, light heads, cameras, etc., to their C-stands: 4-Way Clamp, Baby 5/8-Inch (16mm) Receiver, 66mm Baby 5/8-Inch Stud and this 108mm Baby 5/8-Inch Stud. The baby studs are ideal for securing a second light head to the C-stand riser, eliminating the need for another light stand. Like the other components, it's well made and engineered.Installation is easy: slide into notch on 4-Way Clamp and hand tighten a large locking collar. If I were to do it all again, I’d buy two of the 108mm long studs instead of one 66mm and one 108mm. The greater length allows more room for a softbox.All in all a well made baby pin and near permanent fixture on my Kupo C-stand.
