RAM Mounts Universal Marine Electronic Ball Black 158.7mm 50.8mm 181g

The RAM-111BU is a universal marine electronic ball mount consisting of a 1.5" (38 mm) diameter rubber ball attached at a right angle to a flat rectangular plate measuring approximately 6.25 x 2" (158.7 x 50.8 mm). The plate is finished in black and is intended to provide a secure attachment point for various marine electronic devices. The component has a mass of about 181 g and is suitable for use in boating environments where a durable connection is required.

Advantages

The rubber ball and plate design provides vibration dampening and a sturdy interface for adjustable mounting systems. Pre-drilled hole patterns in the rectangular plate allow compatibility with a range of electronic devices and mounting brackets commonly used in marine applications. The compact dimensions and black finish offer a low-profile, corrosion-resistant appearance that integrates with standard marine hardware.

Suitable for

• Marine GPS units
• CB radios and marine VHF units
• Ham radio installations on boats
• Gimbal brackets and adjustable mounting arms
• Other small marine electronics requiring a plate-to-ball interface

Key specifications

• Ball diameter: 1.5" (approx. 38 mm)
• Plate dimensions: approx. 6.25 x 2" (158.7 x 50.8 mm)
• Material: rubber ball with a rigid mounting plate (black finish)
• Weight: approx. 181 g
• Mounting: plate with multiple pre-drilled hole combinations for device attachment

How to use

Position the rectangular plate against the device or bracket you intend to mount and align the appropriate pre-drilled holes. Fasten the device to the plate using suitable corrosion-resistant hardware (nuts, bolts, or screws) sized to the chosen hole pattern. Insert the rubber ball into a compatible RAM ball socket or arm and secure according to the socket/arm manufacturer's instructions to achieve the desired angle and orientation.

Recommendations

Use stainless-steel or other marine-grade fasteners to prevent corrosion. Periodically check mounting hardware and ball-socket connections for tightness and wear, especially in saltwater environments. Ensure compatibility of hole patterns before installation to avoid drilling additional holes in the electronic device.
