Secure large marine electronics with confidence using the RAM® Large Marine Electronics 2.25" D Ball Mount – Medium Arm. Designed for serious marine environments, this heavy-duty mounting system delivers superior strength, vibration damping, and precise adjustability for fishfinders and chartplotters ranging from 8” to 16”.
This complete mount features a medium-length double socket arm paired with two integrated 2.25" D size rubber balls—one on a 3.68" round drill-down base and the other on a wide 11" x 3" rectangular plate. The oversized D ball system provides exceptional holding power while absorbing shock and vibration, ensuring your electronics stay stable and easy to view even in rough conditions.
Pre-drilled hole patterns on both bases offer broad compatibility with popular marine electronics, and included shoulder washers allow smaller hardware to fit securely into the large mounting holes. Built from powder-coated, marine-grade aluminum, this mount is engineered to resist corrosion and deliver long-term reliability on the water.
