Wooden Universal Ultra Arm v2 (Combo 1/4"-20 & 3/8"-16) is an articulating arm with universal 1/4"-20 and 3/8"-16 interchangeable knobs with non-slip rubber pads on each end and a center double ball clamp. Also included are four locating pins - located in the Ultra Arm base - that can be installed in either variation for a SmallHD or ARRI accessory mount compatible device. 

The updated design of the Universal Ultra Arm v2 (Combo 1/4"-20 & 3/8"-16) can move across 3 planes, giving it a greater range of motion and room for added accessories.

Ultra Arm components are interchangeable so you can use this arm in conjunction with the other options 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 ¼-20 Ultra Ball Knob to ⅜-16 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.
