Mounting Plate RAM Mounts 6.25 x 2 in with Ball Short Arm Base (MPN: DB-RAM-D-115-C)

The RAM-D-115-C is a compact mounting assembly consisting of a base with a 2.25” (D size) ball, a short arm, and a 6.25” x 2” marine electronic plate that also carries a D-size ball. The plate is pre-drilled with multiple hole patterns to directly fit 9”–12” fishfinder gimbal brackets and to support a range of larger marine electronics such as chartplotters and multifunction displays.

Advantages

The combination of a D-size ball base and a short arm provides a rigid, low-profile mounting solution that allows adjustable positioning through the RAM ball-and-socket system. The 6.25” x 2” plate offers multiple pre-drilled hole patterns for direct compatibility with common fishfinder gimbal brackets, reducing the need for adapters. Its compact footprint makes it suitable for installations where space is limited while still supporting larger marine displays.

Suitable for

• Mounting 9”–12” fishfinders with gimbal brackets
• Attaching marine chartplotters and multifunction displays of similar size
• Secure, adjustable mounting of larger marine electronics on boats

Key specifications

• Plate dimensions: 6.25 x 2 inches
• Base ball size: 2.25 inches (D size)
• Arm type: short arm
• Plate style: marine electronic plate with multiple pre-drilled hole patterns
• Compatibility: direct fit for many 9”–12” fishfinder gimbal brackets

How to use

Attach the D-size ball base securely to a flat mounting surface using appropriate fasteners for the substrate. Fasten the electronic plate to the short arm, align the plate’s pre-drilled holes with the device’s gimbal bracket holes, and secure the device using suitable screws. Adjust the display angle by loosening the ball-and-socket joint, positioning the device, then tightening to lock the desired orientation.

Usage recommendations

Use corrosion-resistant fasteners suitable for marine environments and verify that the selected mounting location supports the combined weight of the plate and device. Periodically check and retighten connections and fasteners to maintain a secure installation.
