Double Socket Arm with Round Ball Plate RAM Mounts RAM-103U

The RAM-103U Double Socket Arm with Round Ball Plate is an aluminum mounting arm featuring a 1.5" diameter ball and socket system with one open socket end. It is designed to connect to any RAM mounting base or cradle that uses a 1.5" diameter rubber ball, providing a straightforward solution for adjustable device positioning. The arm has a durable black finish and is intended for use where stable, adjustable mounting is required.

Advantages

The RAM-103U offers a strong yet lightweight aluminum construction and a corrosion-resistant black coating. Its double-socket design enables flexible angle adjustment when paired with compatible RAM ball bases. The open socket end provides compatibility with a wide range of RAM 1.5" ball accessories, while the round ball plate integrates easily with standard RAM bases that use the 1.5" rubber ball.

Suitable for

• Mounting phones, GPS units, tablets, or small devices on vehicle dashboards or consoles when combined with appropriate RAM bases
• Attaching equipment to workbenches, tripods, or instrument panels that accept a 1.5" RAM ball
