The RAM MOUNTS Long Double Socket Arm is a 9.125-inch, double‑socket extension that connects C‑size 1.5" RAM balls to give you wide, stable adjustability for mounting devices.

This long double socket arm expands the reach and articulation of any C‑size RAM ball system so you can position phones, GPS units, tablets, or other accessories exactly where you need them. Built from powder‑coated, marine‑grade aluminum, the arm resists corrosion and stands up to outdoor, marine, and heavy‑use environments. It fits standard C‑size 1.5" RAM ball components and is covered by RAM MOUNTS' lifetime warranty.

How much extra reach and adjustment does this arm give me?

This arm provides a total overall length of 9.125" with an 8" socket‑to‑socket span, allowing for significant extension and flexible positioning between two C‑size 1.5" RAM balls. Its double ball-and-socket joint offers wide tilt and swivel range for near‑infinite angles.

• Overall length: 9.125" from end to end
• Socket‑to‑socket length: 8" between ball centers
• Compatible with any C‑size 1.5" RAM ball components
• Double ball-and-socket design for multi‑axis adjustment

Will this arm stand up to marine and outdoor use?

Yes — the arm is made from powder‑coated, marine‑grade aluminum chosen for corrosion resistance and long life in demanding conditions. The coating protects the underlying metal and preserves appearance after exposure to salt, sun, and moisture.

• Marine‑grade aluminum body resists rust and oxidation
• Durable powder coating prevents surface wear and corrosion
• Suitable for boats, motorcycles, off‑road, and industrial settings

How does it connect to my current RAM system and accessories?

The arm accepts C‑size 1.5" RAM balls on both ends, so it plugs directly into RAM bases, device holders, or adapters that use that ball size. Tightening the clamping knob locks the chosen angle securely while allowing quick readjustment when needed.

• Interfaces with any C‑size (1.5") RAM ball component
• Clamping knob provides secure locking and easy repositioning
• Works as an extender between base and device cradle or between two mounts
