Kinefinity 6 inch StrongArm Articulating Arm

A magic arm is only as good as its lock, and a cheap one sags under a monitor by the second take. This 6 inch arm is machined from metal alloy and rated to hold over 4 kg, which covers a production monitor, a recorder or a small light rather than just a phone clamp.

Three points of articulation give it the reach and angle range to get a finder or a monitor exactly where the operator's eye is, and a single twist handle locks all of them at once, so a repositioning between setups is one movement instead of three. That single-lock design is also what stops it creeping: everything clamps together rather than each joint holding on its own friction.
