Secure, Adjustable Mounting for Large Marine Electronics
The RAM RAMD111CKNOB9H is a heavy-duty 2.25" (D-size) ball mount kit built for securely mounting large chartplotters, fishfinders, GPS units, and other marine electronics on your vessel. The short double socket arm keeps your display close to the surface for a low-profile, vibration-resistant installation — ideal for helm stations, consoles, and dash panels where space is at a premium.
This kit includes everything you need for a complete installation: a 3.68" diameter round base, a 3-3/4" round base, an 11" x 3" rectangular mounting plate, and the RAM Hi-Torq™ Wrench for an extra-firm, tool-free lock on D-size ball arms.
What's in the Box
- Short double socket arm (D-size, 2.25" balls)
- 3.68" diameter round base with pre-drilled holes (two at 180°, three at 120°)
- 3-3/4" round base
- 11" x 3" rectangular plate with multiple pre-drilled hole patterns
- RAM Hi-Torq™ Wrench
Compatible Devices & Mounts
The 11" x 3" plate's multi-pattern hole layout is designed to align with a wide range of marine electronics and mounting hardware, including marine GPS chartplotters, VHF radios, CB and ham radios, and gimbal bracket-style mounts. The round bases accept standard RAM D-size ball accessories, so you can mix and match with other RAM components as your setup evolves.
Pairs well with:
- RAM RAMD115 Universal D Size Ball Mount for 9"–12" Fishfinders & Chartplotters
- RAM RAMD115C Universal D Size Ball Mount for 9"–12" Fishfinders & Chartplotters
- RAM RAMD-201U Standard Length Double Socket Arm for 2.25" Balls

Parts Desk Insights
Best use case: This kit is the go-to choice when mounting a large-screen chartplotter or fishfinder (typically 9"–16") on a flat helm surface where you want a rigid, low-profile installation. The short arm minimizes flex and wobble at speed — a meaningful advantage in rough water. The Hi-Torq™ wrench is especially useful in cold-weather boating when gloves make hand-tightening difficult. If you need more reach or tilt range, consider the standard-arm version (RAM RAMD-111U) instead.
