TWIST Ball Monitor Arm 3 Inch with ARRI 1/4-20 + ARRI 1/4-20 Spuds is an articulating arm with interchangeable mounting spuds that utilize a variable friction 15mm clamp. With the variable friction design, you can grab and twist the arm or monitor without loosening a thumbscrew. To customize your own TWIST Ball mount, check out this page.
Included in this kit are two ARRI 1/4-20, which have removable 3mm locating pins in 10.4mm spacing from center to center. Pins can also be installed with 15mm spacing, which can be found on some random, 3rd party products.
Install the bottom spud on your camera or cheeseplate and the top spud on your monitor or accessory, then slip the TWIST Balls into place and lock the thumbscrews.
The Speedball Clamp's "Chip Clip" design allows for easy, annoyance-free installation, and the ratcheting thumbscrew can be pulled out and repositioned.
3-inch arm includes the Speedball Extension, a second Speedball Clamp, and a hook and loop cable tie.
TWIST Ball components are compatible with our Universal Speedball and any other brand of 1-inch (25mm) ball attachment like Ultralight Control Systems, Wooden Camera, etc.
