RAM Mounts Double Socket Arm

This mount is specifically designed for action cameras that utilize a standard 1/4"-20 threaded mounting hole. It is not intended for smartphones unless you have a separate adapter that connects to a 1/4"-20 thread.

The double socket arm features a central adjustment knob that allows you to loosen the grip on the ball joints at both ends. This gives you nearly infinite articulation, letting you tilt, rotate, and angle your camera exactly where you need it.

Yes, this arm is part of the RAM modular system. It is compatible with any RAM B-size ball base, allowing you to mix and match bases, arms, and cradles to build a custom mounting solution.

Once you have positioned your device, tightening the central knob locks both ball joints simultaneously. This creates a very rigid hold that resists vibration and movement, even during active use.

The 2.5 lbs refers to the weight of the mount itself. While it is built with durable materials, please ensure your camera setup does not exceed the recommended weight capacity for B-size RAM components, which is typically around 2 lbs for high-vibration environments.
