Ultra Arm components are interchangeable so you can use this arm in conjunction with the other options we make like 3/8-16, NATO Clamp, Hot Shoe, and Super Clamp. You can also add a center extension piece and second Double Ball Clamp! Many existing 3rd party 25mm ball systems are compatible as well.
Easily swap from 1/4-20 Ultra Ball Knob to 3/8-16 Ultra Ball Knob by depressing the brass pin and sliding out. Four locating pins are included in the Ultra Arm base and can be installed in either SmallHD or ARRI Standard spacing for securely mounting accessories.
Great for attaching LCDs, lights, audio recorders and much more!
