Promaster 7″ Articulating Arm Supply

The Arm of Promaster

The ProMaster 7″ Articulating Arm is a versatile solution for mounting a variety of accessories to your camera rig or tripod at almost any angle. Ideal for attaching an LCD monitor, microphone, sound equipment, small light, or phone/tablet (with the appropriate clamp), it offers flexibility with its ARRI-style retractable pins. These pins allow compatibility with ¼”-20, standard 3/8”-16 connections (with an included adapter), or ARRI-style connections. The arm features ¼”-20 male screws and ball heads at both ends, with a secure pivot joint using two facing rosettes to prevent slippage. A single-point locking knob ensures quick and easy adjustments, loosening or tightening all joints simultaneously. Additionally, the cold foot and spacer are removable, revealing a common ¼”-20 male screw or female threaded port for further mounting options.
