The RAM Mounts Diamond Ball Base RAM-238U features a 3.81 cm ball diameter made from durable aluminum. This black base is designed for versatile mounting solutions, ensuring stability and reliability for various applications. Ideal for use in vehicles, boats, or any setting requiring secure mounting.

## Long description

The RAM-238U features a 1.5" (3.81 cm) diameter rubber-coated ball set at a right angle to a diamond-shaped aluminium base measuring approximately 2.43" x 1.31". The diamond base includes two mounting holes spaced 1.912" (center-to-center) and conforms to the industry-standard AMPS hole pattern, allowing compatibility with a wide range of RAM Mount and third-party cradles and arms.
Advantages
The aluminium diamond base provides durable, lightweight support while the rubber-coated 1.5" ball offers a secure friction fit with standard RAM ball-and-socket components. Its AMPS-compatible hole pattern makes it easy to integrate with many cradles and accessories without additional adapters. The compact footprint and right-angle ball orientation allow flexible positioning in tight spaces.

How to use
