NATO Lock Ultra Arm (3") is an articulating arm with two sets of 25mm (1 inch) double ball joints which allow a monitor or accessory to be positioned in just about any orientation.
Features NATO standard quick release and clamp on each end. Black center thumbscrews ratchet to allow for easy positioning. The 3" title refers to the center extension length but actual length fully extended measures 240mm (9.4 inches).
The rail portion can bolt into a 1/4-20 or 3/8-16 hole using the included screws. Set screw can also be installed to prevent twisting.
The rail is also threaded for 1/4-20 and 3/8-16 so accessories can screw into it.
The clamp portion of the kit can also bolt into a 1/4-20 or 3/8-16 hole using the included screws and it is also threaded for 1/4-20 and 3/8-16 so accessories can screw into it.
Ultra Arm components are interchangeable so you can use this arm in conjunction with the other options we make like 1/4-20, 3/8-16, Hot Shoe, and Super Clamp. You can also change the center extension piece! Many existing 3rd party 25mm ball systems are compatible as well.
Great for attaching LCDs, lights, audio recorders and much more!
