The RAM Mounts RAMD111CKNOB9H is a heavy-duty marine electronics mounting kit built around RAM's proven D-size 2.25" ball and socket system. Engineered for large fishfinders and chartplotters such as the Lowrance HDS-16, this kit delivers rock-solid stability on the water while offering near-infinite adjustability for the perfect viewing angle.
The kit includes a 3.68" diameter round drill-down base, a short double socket arm, and an 11" x 3" rectangular electronics plate. The round base features pre-drilled mounting holes in two configurations — two holes at 180° and three holes at 120° — for flexible installation on any flat surface. The rectangular plate includes multiple combinations of pre-drilled holes designed to match up with a wide range of marine electronics and mounting hardware, including Marine GPS units, CB radios, ham radios, and gimbal brackets.
Key Features:
- D-Size 2.25" rubber ball for maximum strength and vibration damping
- 3.68" diameter round base with pre-drilled holes (2-hole 180° and 3-hole 120° patterns)
- 11" x 3" rectangular plate with multiple pre-drilled hole configurations for broad device compatibility
- Short double socket arm with overall height of 8.125"
- Powder-coated marine-grade aluminum construction for corrosion resistance
- Supports up to 15 lbs. of device weight
- Compatible with Lowrance, Garmin, Humminbird, and Raymarine fishfinders and GPS chartplotters
- Includes the RAM Hi-Torq™ Wrench for an extra-tight knob grip on D-size ball arms — especially useful in cold weather or demanding marine environments
The included RAM Hi-Torq™ Wrench is specifically designed for use with the knob on D-size ball arms and mounts, providing a secure, tool-free tightening solution when gloves or cold conditions make hand-tightening difficult. This mount is an ideal solution for anglers and boaters who demand a reliable, adjustable mount for large-screen marine electronics.
