Kupo KS-103 Double Ball Joint Adapter with Dual 5/8"""" (16mm) Studs

Kupo KS-103 Double Ball Joint Adapter with Dual 5/8" (16mm) Studs – Ratcheted Handle for Secure, Rotation-Resistant Mounting

The Kupo KS-103 is a double ball joint adapter that provides flexible, secure positioning for lights and accessories. It uses a ratcheted handle to lock the ball joint in place and two 5/8" (16mm) studs on either side for mounting options. One stud is tapped with a 1/4"-20 female thread while the other has a 3/8"-16 female thread, giving you common thread choices for accessories and fixtures.

Main features

• The adapter uses a double ball joint secured by a ratcheted handle, so you can position fixtures precisely and lock them firmly.
• It includes two 5/8" (16mm) studs—one tapped for 1/4"-20 female thread and the other tapped for 3/8"-16 female thread—to accommodate different mounting hardware.
• Each stud is milled with six flat surfaces. These flats prevent a light fixture or any accessory with a baby receiver from rotating once the set-screw is tightened.
• Both ball joint studs are designed to fit into baby sockets for Convi Clamp or Super Viser, ensuring compatibility with common grip equipment.
• The adapter allows you to clamp onto supports at odd angles, including stands or suction cups, enabling flexible placement in tight or unconventional setups.

Usage and compatibility

Use the KS-103 when you need flexible articulation combined with reliable locking. The dual studs give you a choice of thread sizes for mounting fixtures and small accessories. Because both studs fit baby sockets for Convi Clamp and Super Viser, you can integrate this adapter with standard grip equipment. Additionally, the six flat surfaces on each stud make it suitable for accessories with baby receivers that require anti-rotation security.

How it secures accessories

The ratcheted handle locks the double ball joint so you can set angle and tension precisely. After you insert a fixture or accessory into a stud and tighten the set-screw, the six milled flats on each stud prevent that item from rotating. In practice, this keeps lights and receivers stable during adjustments or on-location moves.
