# Universal Speedball Monitor Arm (3 Inch)

Universal Speedball Monitor Arm (3 Inch) is an articulating arm with combination 1/4-20 and 3/8-16 mounting screws on each end, two double-ball clamps, and one 3 inch (75mm) extension with velcro cable wrap.

Each ball end contains both mounting thread standards. Push the 3/8-16 outer screw down to reveal the hidden 1/4-20.

Install the ball with the cam-lever in the down position to finger-tight, then lift the lever to add extra locking force to the assembly. The extra force of the cam-lever design allows the arm to lock in place without the use of messy rubber pads.

The "Chip Clip" clamp design allows for easy, annoyance-free installation, and the ratcheting thumbscrew can be pulled out and repositioned.

3 inch arm has pass-through holes for 1/4-20 and 3/8-16 screws.

Universal Speedball components are compatible with any other brand of 1 inch (25mm) ball attachment like Ultralight Control Systems, Wooden Camera, etc.
