## Summary description

RAM Mounts Diamond Ball Base is a compact black mounting base designed to secure RAM ball assemblies. Weighing 50 g, it provides a stable attachment point for compatible RAM ball-and-socket arms and device holders. Suitable for installing accessories in vehicles, boats or workstations where a low-profile, durable base is required.

## Long description

The RAM-B-238U Diamond Ball Base features a B-size 1" diameter rubber ball attached to a diamond-shaped mounting plate. The plate measures 2.43" x 1.31" and includes two mounting holes spaced 1.912" center-to-center, matching the industry-standard AMPS hole pattern to allow connection with a wide range of RAM Mounts products and compatible third-party cradles.
Advantages
The rubber ball provides vibration dampening and secure articulation, while the diamond plate with AMPS hole pattern ensures broad compatibility with mounts and cradles. The compact, lightweight design (approximately 50 g) simplifies installation and reduces added bulk when used in vehicle, marine, or industrial mounting setups.
Suitable for
 Mounting RAM arms and cradles that use AMPS hole pattern
 Attaching small devices or holders in vehicles, boats, or workstations
