Jobu Design QRR-138 Ballhead Threaded Hole Quick Release Clamp

Upgrade Your Ball Head to Arca-Swiss Compatibility

The Jobu Design QRR-138 Quick Release Clamp is a simple and effective upgrade for photographers looking to replace proprietary clamps with a universal Arca-Swiss compatible system. Designed with a 3/8"-16 threaded socket, it mounts directly onto ball heads, monopods, and other support systems with a standard threaded stud.

If you're working with older or non-standard quick release systems, the QRR-138 allows you to modernise your setup for greater flexibility and compatibility.
