OVERVIEW
- Interchangeable Mounting Knobs
- Removable Anti-Twist Pins
- Compatible with 25mm Ball Systems
This Universal Ultra Arm Ball from Wooden Camera is a replacement ball joint for Wooden Camera’s Ultra Arm system, as well as third-party systems that use a 25mm ball. It features interchangeable threaded screw knobs, one with a 1/4″-20 threaded screw and one with a 3/8″-16 screw. This allows you to mount a variety of accessories onto your arm by swapping the original ball for this one. The included removable anti-twist divots allow you to securely lock this arm to compatible accessories to prevent it from twisting unexpectedly. Changing the mounting knobs is a simple task; simply depress the brass locking pin, allowing the knobs to be swapped out.
