Product 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.


  • The included 1/4"-20 and 3/8"-16 knobs and removable anti-twist pins allow you to use the arm with the most common mounting threads
  • The arm is compatible with third-party 25mm ball systems
